	'''''Friendly fire''''' (''']''' or '''non-hostile fire''') is a term originally adopted by the ] in reference to an attack on friendly forces by other friendly forces, which may be deliberate (e.g. incorrectly identifying the target as the ]), or accidental (e.g. missing the enemy and hitting "friendlies"). Friendly fire is contrasted with ] originating from ] forces ("enemy fire"). In a friendly fire incident personnel may be killed, or material assets may be damaged or destroyed. Friendly fire is one kind of ].

	In the Philippines, the miltary term for a friendly fire incident is a ''misencounter.''

			Friendly fire should not be confused with ], which is the uncondoned ''intentional'' (or attempted) killing of servicemen by fellow personnel serving on the same side.
	==Fratricide versus Friendly Fire==

			==History==
	Some prefer the term ''fratricide'' over ''friendly fire'', because they deem the latter to be an unfitting ] exemplified by the ] "there's nothing friendly about getting shot by your own side." However, the origin and purpose of the term is as a simple distinction to ''enemy fire''. Both terms serve only to identify the ''source of an attack'' as coming from enemy (hostile) or friendly forces and not the ''nature of an attack''.
			Paul R. Syms argues that friendly fire is an ancient phenomenon.<ref>Kirke, Charles (ed.). 2010. ''Fratricide in Battle: (Un)Friendly Fire''. London: Bloomsbury, p. 7.</ref> He notes recorded events in Ancient Greece and other early accounts of battles. He and other historians also note that weapons such as guns, artillery, and aircraft dramatically increased friendly-fire casualties.

			By the 20th and 21st centuries, friendly-fire casualties have likely become a significant percentage of combat injuries and fatalities. ] provides an overview of American casualties during and since the ]:
	The term ] (killing of a friend) has also been used in the same manner as fratricide (Shrader 1982).
			{{blockquote\|While acknowledging that the "statistical dimensions of the friendly fire problem have yet to be defined; reliable data are simply not available in most cases," ''The Oxford Companion to American Military History'' estimates that between 2 percent and 25 percent of the casualties in America's wars are attributable to friendly fire.<ref>Krakauer, Jon. 2010. ''Where Men Win Glory: The Odyssey of Pat Tillman'', NY: Anchor Books, p. 405.</ref> }}

	==~~Classification~~==		==Under-reporting==
			In the annals of warfare, deaths at the hand of the enemy are often valorized, while those at the hand of friendly forces may be cast in shame. Moreover, because ] and ] are important, especially in modern warfare, the military may be inclined to under-report incidents of friendly-fire, especially when in charge of both investigations and ]:
	Friendly fire incidents fall roughly into two categories.
			{{Blockquote\|text=If ] is an untoward but inevitable aspect of warfare, so, too, is the tendency by military commanders to sweep such tragedies under the rug. It's part of a larger pattern: the temptation among generals and politicians to control how the press portrays their military campaigns, which all too often leads them to misrepresent the truth in order to bolster public support for the war of the moment.\|author=Jon Krakauer \|source=''Where Men Win Glory''. NY: Bloomsbury, p. 205.}}
	The first classification is '''Fog of war''' which generically describes friendly fire incidents in unintentional circumstances.
			Although there may well be a longstanding history of such bias,<ref>Claire Outteridge, Simon Henderson, Raphael Pascual, Paul Shanahan, "How can Human Factors be Exploited to Reduce the Risk of Fratricide?" in Kirke, p. 115</ref><ref>Krakauer, Jon. 2009. Where Men Win Glory. NY: Bloomsbury, p. 204.</ref> Krakauer claims "the scale and sophistication of these recent ] efforts, and the unabashedness of their executors" in Iraq and Afghanistan is new.<ref>Krakauer, Jon. 2009. ''Where Men Win Glory''. NY: Bloomsbury, p. 205.</ref>
	The second classification is '''murder''' where friendly fire incidents are premeditated. During the Vietnam War, this was known as ].

			==Causes==
	Fog of war incidents fall roughly into two classes:
			===Fog of war===
	*the first is due to errors of position, where fire aimed at enemy forces accidentally ends up hitting one's own. Such incidents were relatively common during ] and ], where troops fought in proximity to each other and targeting was relatively inaccurate. As weapons have become more accurate in recent times, this class of incidents has become less common but is still possible, the most recent and highly publicized example being ], wherein a ] was mistakenly called in on friendly forces, causing massive casualties.
			Friendly fire can arise from the "]" – the confusion inherent in warfare. Friendly fire that is the result of apparent recklessness or incompetence may be improperly lumped into this category. The concept of a fog of war has come under considerable criticism, as it can be used as an excuse for poor planning, weak or compromised intelligence and incompetent command.<ref name=Regan/>

			===Errors of position===
	*the second class is due to errors of identification, where friendly troops are mistakenly attacked in the belief that they are enemy. Highly mobile battles, and battles involving troops from many nations are more likely to cause this kind of incident as evidenced by incidents in the first ].
			Errors of position occur when fire aimed at enemy forces may accidentally end up hitting one's own. Such incidents are exacerbated by close proximity of combatants and were relatively common during the First and Second World Wars, where troops fought in close combat and targeting was relatively inaccurate. As the accuracy of weapons improved, this class of incident has become less common but still occurs.

			===Errors of identification===
	==Friendly fire in the U.S. military==
			Errors of identification happen when friendly troops are mistakenly attacked in the belief that they are the enemy. Highly mobile battles, and battles involving troops from many nations are more likely to cause this kind of incident as evidenced by incidents in the 1991 ], or the shooting down of a British aircraft by a U.S. ] during the ].<ref>The Economist ''Closing in on Baghdad'' 25 March 2003</ref> In the ], four Canadian soldiers were killed and eight others injured when a ] major dropped a 500 lb (230 kg) bomb from his ] onto the ] regiment which was conducting a night firing exercise near Kandahar.<ref>].

			During ], "]" were painted on ] ] to assist identification in preparation for the ]. ] when the ] was first introduced into use as it was otherwise very similar in profile to a German aircraft.

Graham was a former Canadian Olympic althlete who competed on the Canadian 4x400 Men's Relay Team at the 1992 Barcelona Olympics.

			===Errors of response inhibition===
	== History ==
			Errors of response inhibition have recently been proposed as another potential cause of some friendly fire accidents.<ref>Biggs, A. T., Cain, M. S., & Mitroff, S. R. (2015). Cognitive training can reduce civilian casualties in a simulated shooting environment. Psychological science, 26(8), 1164–1176. {{doi\|10.1177/0956797615579274}}</ref><ref>Wilson, K.

Human Factors: The Journal of the Human Factors and Ergonomics Society, {{doi\|10.1177/0018720815605703}}</ref> These types of errors are different from visual misidentification, and instead appear to be caused by a failure to inhibit a shooting response.
	Two French regiments accidentally attacking each other during the ] led to the habit of attaching a white scarf to the flags of the regiments from 1690 - white being the colour of the kings of France.

			A number of situations can lead to or exacerbate the risk of friendly fire. Difficult terrain and visibility are major factors. Soldiers fighting on unfamiliar ground can become disoriented more easily than on familiar terrain. The direction from which enemy fire comes may not be easy to identify, and poor weather conditions and combat stress may add to the confusion, especially if fire is exchanged. Accurate navigation and fire discipline are vital. In high-risk situations, leaders need to ensure units are properly informed of the location of friendly units and must issue clear, unambiguous orders, but they must also react correctly to responses from soldiers who are capable of using their own judgement. Miscommunication can be deadly. Radios, field telephones, and signalling systems can be used to address the problem, but when these systems are used to co-ordinate multiple forces such as ground troops and aircraft, their breakdown can dramatically increase the risk of friendly fire. When allied troops are operating, the situation is even more complex, especially with language barriers to overcome.<ref name="Kirke"/>

	==~~Cultural~~ ~~Views~~==		==Impact reduction==
	Many in other nations - particularly those in Britain - hold the view that the US has a severe record of friendly fire. The popular opinion is that the US is more likely to injure its own or its unfortunate allies, the British, than anyone of an opposing army. However, a more accurate view is that the United States, as a world superpower, is simply more likely to have "friendly fire" events because the US is much more likely to be involved in combat operations. Whether it was the Korean War, the Vietnam War, Operation Desert Shield/Storm, the War in Kosovo and the Global War on Terror (GWOT), the US has provided the overwhelming majority of combat forces. By sheer numbers, the odds are that the US will have more casualties, regardless of whether they are from enemy or friendly fire.

			Some analyses dismiss the material impact of friendly fire, by concluding friendly-fire casualties are usually too few to affect the outcome of a battle.<ref>{{in lang\|fr}} Percin, Gen. Alexandre (1921) ''Le Massacre de Notre Infanterie 1914–1918'', Michel Albin, Paris;</ref><ref>Shrader, Charles R.

Troops expect to be targeted by the enemy, but being hit by their own forces has a huge negative impact on morale. Forces doubt the competence of their command, and its prevalence makes commanders more cautious in the field.<ref name="uYxiz6P0KsEC">{{cite book\|url=https://books.google.com/books?id=uYxiz6P0KsEC&pg=PA4 \|title=Who goes there : friend or foe? \|author=Office of Technology Assessment \|year=1993 \|publisher=Diane Publishing \|isbn=9781428921139 \|access-date=4 January 2011}}{{Page needed\|date=July 2011}}</ref>
	Furthermore, since the Allied forces usually completely annihilate their opposition(citation needed, see talk), little is known about "friendly fire" incidents for non-allied opposition forces. The Allied forces, especially the British and Americans, are able to attain good situational awareness on the modern battlefield and when an unfortunate "friendly fire" incident occurs, the events are much more likely to be investigated, analyzed and adjudicated to learn exactly what happened, and if possible, why.

			Attempts to reduce this effect by military leaders involve identifying the causes of friendly fire and overcoming repetition of the incident through training, tactics and technology.<ref name="Kirke">Kirke, Charles M. (ed., 2012) ''Fratricide in Battle: (Un)Friendly Fire'' {{Webarchive\|url=https://wayback.archive-it.org/all/20171011073806/https://www.ebookweek.com/fat-obliterator-review/ \|date=11 October 2017 }}</ref>
	==Distinction==

	Friendly fire is fire which was intended to do harm to the enemy; a death resulting from a ] is not considered "friendly fire".
			===Training===
			] Joint Maneuver Training Center during Bold Quest 2011, a combat assessment exercise to test the interoperability of target identification systems of different allied nations to reduce friendly fire incidents.]]
			Most militaries use extensive training to ensure troop safety as part of normal coordination and planning, but are not always exposed to possible friendly-fire situations to ensure they are aware of situations where the risk is high. Difficult terrain and bad weather cannot be controlled, but soldiers must be trained to operate effectively in these conditions, as well as being trained to fight at night. Such simulated training is now commonplace for soldiers worldwide. Avoiding friendly fire can be as straightforward as ensuring fire discipline is instilled in troops, so that they fire and cease firing when they are told to. Firing ranges now also include ].<ref name="uYxiz6P0KsEC"/>

			The increasing sophistication of weaponry, and the tactics employed against American forces to deliberately confuse them has meant that while overall casualties have fallen for American soldiers in the late 20th and 21st centuries, the overall percentage of deaths due to friendly fire in American actions has risen dramatically. In the 1991 Gulf War, most of the Americans killed by their own forces were crew members of armored vehicles hit by anti-tank rounds. The response in training includes recognition training for Apache helicopter crews to help them distinguish American tanks and armored vehicles at night and in bad weather from those of the enemy. In addition, tank gunners must watch for "friendly" robotic tanks that pop out on training courses in California's Mojave Desert. They also study video footage to help them recognize American forces in battle more quickly.<ref name=autogenerated1>{{cite news \|last=Schmitt \|first=Eric \|url=https://query.nytimes.com/gst/fullpage.html?res=9D0CE6DF1E3FF93AA35751C1A967958260 \|title=U.S. Striving to Prevent 'Friendly Fire' \|location=Middle East \|work=The New York Times \|date=9 December 1991 \|access-date=4 January 2011 \|archive-date=25 January 2022 \|archive-url=https://web.archive.org/web/20220125063247/https://www.nytimes.com/1991/12/09/us/us-striving-to-prevent-friendly-fire.html \|url-status=live }}</ref>

			===Technological fixes===

			Improved technology to assist in identifying friendly forces is also an ongoing response to friendly fire problems.
			From the earliest days of warfare, identification systems were visual and developed into extremely elaborate suits of armour with distinctive ] patterns. During the ], Admiral Nelson ordered that ships under his command adopt a common paint scheme to reduce friendly fire incidents; this pattern became known as the ]. ] served a similar function during the Allied invasion of Normandy in World War II. When ] was developed during World War II, IFF ("]") systems to identify aircraft developed into a multitude of radio beacons.

			Correct ] is vital to ensuring units know where they are in relation to their own force and the enemy. Efforts to provide accurate compasses inside metal boxes in tanks and trucks has proven difficult, with ] a major breakthrough.

			Other technological changes include hand-held navigational devices that use ] signals, giving ground forces the exact location of enemy forces as well as their own. The use of infrared lights and ] that are invisible to observers without night-goggles, or fibres and dyes that reflect only specific wavelengths are developing into key identifiers for friendly infantry units at night.

			There is also some development of remote sensors to detect enemy vehicles – the Remotely Monitored Battlefield Sensor System (REMBASS) uses a combination of ], seismic vibration, and infrared to not just detect, but identify vehicles.<ref name="uYxiz6P0KsEC"/>

			===Tactics===

			Some ] make friendly fire virtually inevitable, such as the practice of dropping barrages of mortars on enemy ] posts in the final moments before capture. This practice continued throughout the 20th century since machine guns were first used in World War I. The high friendly fire risk has generally been accepted by troops since machine gun emplacements are tactically so valuable, and at the same time so dangerous that the attackers wanted them to be shelled, considering the shells far less deadly than the machine guns.<ref name="uYxiz6P0KsEC"/>
			Tactical adjustments include the use of "kill boxes", or zones that are placed off-limits to ground forces while allied aircraft attack targets, which goes back to the beginning of military aircraft in World War I.<ref name=autogenerated1/>

			The ] battle tactics adopted by the American military – overwhelming power, battlefield awareness, dominant maneuvers, and spectacular displays of force – are employed because they are believed to be the best way to win a war quickly and decisively, reducing casualties on both sides. However, if the only people doing the shooting are American, then a high percentage of total casualties are bound to be the result of friendly fire, blunting the effectiveness of the shock and awe tactic. It is probably the fact that friendly fire has proven to be the only fundamental weakness of the tactics that has caused the American military to take significant steps to overturn a blasé attitude to friendly fire and assess ways to eliminate it.<ref name="uYxiz6P0KsEC"/>

			=== Markings ===

			During ], codename for the ], on the night of 11 July 1943, American ]s were mistakenly fired upon by American ground and naval forces and 23 planes were shot down and 37 damaged, resulting in 318 casualties, with 60 airmen and 81 paratroopers killed.<ref>{{cite web \| title = Airborne Reinforcement \| work = US Army in World War II \| url = http://www.ibiblio.org/hyperwar/USA/USA-MTO-Sicily/USA-MTO-Sicily-9.html \| access-date =10 March 2009 }}</ref>

Accidental attack on friendly forces This article is about unintentional incidents. For institutionalised, intentional instances of fratricide, see barrier troops. For other uses, see Friendly Fire (disambiguation).

In military terminology, friendly fire or fratricide is an attack by belligerent or neutral forces on friendly troops while attempting to attack enemy or hostile targets. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack enemy or hostile targets, and deliberate firing on one's own troops for disciplinary reasons is not called friendly fire, and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting.

Use of the term friendly in a military context for allied personnel started during the First World War, often when shells fell short of the targeted enemy. The term friendly fire was originally adopted by the United States military; S.L.A. Marshall used the term in Men Against Fire in 1947. Many North Atlantic Treaty Organization (NATO) militaries refer to these incidents as blue on blue, which derives from military exercises where NATO forces were identified by blue pennants and units representing Warsaw Pact forces by red pennants. In classical forms of warfare where hand-to-hand combat dominated, death from a "friendly" was rare, but in industrialized warfare, deaths from friendly fire are more common.

Friendly fire should not be confused with fragging, which is the uncondoned intentional (or attempted) killing of servicemen by fellow personnel serving on the same side.

History

Paul R. Syms argues that friendly fire is an ancient phenomenon. He notes recorded events in Ancient Greece and other early accounts of battles. He and other historians also note that weapons such as guns, artillery, and aircraft dramatically increased friendly-fire casualties.

By the 20th and 21st centuries, friendly-fire casualties have likely become a significant percentage of combat injuries and fatalities. Jon Krakauer provides an overview of American casualties during and since the Second World War:

While acknowledging that the "statistical dimensions of the friendly fire problem have yet to be defined; reliable data are simply not available in most cases," The Oxford Companion to American Military History estimates that between 2 percent and 25 percent of the casualties in America's wars are attributable to friendly fire.

Under-reporting

In the annals of warfare, deaths at the hand of the enemy are often valorized, while those at the hand of friendly forces may be cast in shame. Moreover, because public relations and morale are important, especially in modern warfare, the military may be inclined to under-report incidents of friendly-fire, especially when in charge of both investigations and press releases:

If fratricide is an untoward but inevitable aspect of warfare, so, too, is the tendency by military commanders to sweep such tragedies under the rug. It's part of a larger pattern: the temptation among generals and politicians to control how the press portrays their military campaigns, which all too often leads them to misrepresent the truth in order to bolster public support for the war of the moment.
— Jon Krakauer, Where Men Win Glory. NY: Bloomsbury, p. 205.

Although there may well be a longstanding history of such bias, Krakauer claims "the scale and sophistication of these recent propaganda efforts, and the unabashedness of their executors" in Iraq and Afghanistan is new.

Causes

Fog of war

Friendly fire can arise from the "fog of war" – the confusion inherent in warfare. Friendly fire that is the result of apparent recklessness or incompetence may be improperly lumped into this category. The concept of a fog of war has come under considerable criticism, as it can be used as an excuse for poor planning, weak or compromised intelligence and incompetent command.

Errors of position

Errors of position occur when fire aimed at enemy forces may accidentally end up hitting one's own. Such incidents are exacerbated by close proximity of combatants and were relatively common during the First and Second World Wars, where troops fought in close combat and targeting was relatively inaccurate. As the accuracy of weapons improved, this class of incident has become less common but still occurs.

Errors of identification

Errors of identification happen when friendly troops are mistakenly attacked in the belief that they are the enemy. Highly mobile battles, and battles involving troops from many nations are more likely to cause this kind of incident as evidenced by incidents in the 1991 Gulf War, or the shooting down of a British aircraft by a U.S. Patriot battery during the 2003 invasion of Iraq. In the Tarnak Farm incident, four Canadian soldiers were killed and eight others injured when a U.S. Air National Guard major dropped a 500 lb (230 kg) bomb from his F-16 onto the Princess Patricia's Canadian Light Infantry regiment which was conducting a night firing exercise near Kandahar. Another case of such an accident was the death of Pat Tillman in Afghanistan, although the exact circumstances of that incident are yet to be definitively determined.

During World War II, "invasion stripes" were painted on Allied aircraft to assist identification in preparation for the invasion of Normandy. Similar markings had been used when the Hawker Typhoon was first introduced into use as it was otherwise very similar in profile to a German aircraft. Late in the war the "protection squadron" that covered the elite German jet fighter squadron as it landed or took off were brightly painted to distinguish them from raiding Allied fighters.

Errors of response inhibition

Errors of response inhibition have recently been proposed as another potential cause of some friendly fire accidents. These types of errors are different from visual misidentification, and instead appear to be caused by a failure to inhibit a shooting response.

A number of situations can lead to or exacerbate the risk of friendly fire. Difficult terrain and visibility are major factors. Soldiers fighting on unfamiliar ground can become disoriented more easily than on familiar terrain. The direction from which enemy fire comes may not be easy to identify, and poor weather conditions and combat stress may add to the confusion, especially if fire is exchanged. Accurate navigation and fire discipline are vital. In high-risk situations, leaders need to ensure units are properly informed of the location of friendly units and must issue clear, unambiguous orders, but they must also react correctly to responses from soldiers who are capable of using their own judgement. Miscommunication can be deadly. Radios, field telephones, and signalling systems can be used to address the problem, but when these systems are used to co-ordinate multiple forces such as ground troops and aircraft, their breakdown can dramatically increase the risk of friendly fire. When allied troops are operating, the situation is even more complex, especially with language barriers to overcome.

Impact reduction

Some analyses dismiss the material impact of friendly fire, by concluding friendly-fire casualties are usually too few to affect the outcome of a battle. The effects of friendly fire, however, are not just material. Troops expect to be targeted by the enemy, but being hit by their own forces has a huge negative impact on morale. Forces doubt the competence of their command, and its prevalence makes commanders more cautious in the field.

Attempts to reduce this effect by military leaders involve identifying the causes of friendly fire and overcoming repetition of the incident through training, tactics and technology.

Training

Most militaries use extensive training to ensure troop safety as part of normal coordination and planning, but are not always exposed to possible friendly-fire situations to ensure they are aware of situations where the risk is high. Difficult terrain and bad weather cannot be controlled, but soldiers must be trained to operate effectively in these conditions, as well as being trained to fight at night. Such simulated training is now commonplace for soldiers worldwide. Avoiding friendly fire can be as straightforward as ensuring fire discipline is instilled in troops, so that they fire and cease firing when they are told to. Firing ranges now also include "don't fire" targets.

The increasing sophistication of weaponry, and the tactics employed against American forces to deliberately confuse them has meant that while overall casualties have fallen for American soldiers in the late 20th and 21st centuries, the overall percentage of deaths due to friendly fire in American actions has risen dramatically. In the 1991 Gulf War, most of the Americans killed by their own forces were crew members of armored vehicles hit by anti-tank rounds. The response in training includes recognition training for Apache helicopter crews to help them distinguish American tanks and armored vehicles at night and in bad weather from those of the enemy. In addition, tank gunners must watch for "friendly" robotic tanks that pop out on training courses in California's Mojave Desert. They also study video footage to help them recognize American forces in battle more quickly.

Technological fixes

Improved technology to assist in identifying friendly forces is also an ongoing response to friendly fire problems. From the earliest days of warfare, identification systems were visual and developed into extremely elaborate suits of armour with distinctive heraldic patterns. During the Napoleonic Wars, Admiral Nelson ordered that ships under his command adopt a common paint scheme to reduce friendly fire incidents; this pattern became known as the Nelson Chequer. Invasion stripes served a similar function during the Allied invasion of Normandy in World War II. When radar was developed during World War II, IFF ("Identification friend or foe") systems to identify aircraft developed into a multitude of radio beacons.

Correct navigation is vital to ensuring units know where they are in relation to their own force and the enemy. Efforts to provide accurate compasses inside metal boxes in tanks and trucks has proven difficult, with GPS a major breakthrough.

Other technological changes include hand-held navigational devices that use satellite signals, giving ground forces the exact location of enemy forces as well as their own. The use of infrared lights and thermal tape that are invisible to observers without night-goggles, or fibres and dyes that reflect only specific wavelengths are developing into key identifiers for friendly infantry units at night.

There is also some development of remote sensors to detect enemy vehicles – the Remotely Monitored Battlefield Sensor System (REMBASS) uses a combination of acoustic, seismic vibration, and infrared to not just detect, but identify vehicles.

Tactics

Some tactics make friendly fire virtually inevitable, such as the practice of dropping barrages of mortars on enemy machine gun posts in the final moments before capture. This practice continued throughout the 20th century since machine guns were first used in World War I. The high friendly fire risk has generally been accepted by troops since machine gun emplacements are tactically so valuable, and at the same time so dangerous that the attackers wanted them to be shelled, considering the shells far less deadly than the machine guns. Tactical adjustments include the use of "kill boxes", or zones that are placed off-limits to ground forces while allied aircraft attack targets, which goes back to the beginning of military aircraft in World War I.

The shock and awe battle tactics adopted by the American military – overwhelming power, battlefield awareness, dominant maneuvers, and spectacular displays of force – are employed because they are believed to be the best way to win a war quickly and decisively, reducing casualties on both sides. However, if the only people doing the shooting are American, then a high percentage of total casualties are bound to be the result of friendly fire, blunting the effectiveness of the shock and awe tactic. It is probably the fact that friendly fire has proven to be the only fundamental weakness of the tactics that has caused the American military to take significant steps to overturn a blasé attitude to friendly fire and assess ways to eliminate it.

Markings

During Operation Husky, codename for the Allied invasion of Sicily, on the night of 11 July 1943, American C-47 transport planes were mistakenly fired upon by American ground and naval forces and 23 planes were shot down and 37 damaged, resulting in 318 casualties, with 60 airmen and 81 paratroopers killed.

This led to the use of Invasion stripes that were used during D-Day as a visible way to prevent friendly fire. During the Russian invasion of Ukraine the Z (military symbol) has been used on Russian vehicles as a form of marking. There are various explanations as to its meaning, however, one is that both sides are using the same equipment. Ukrainian forces have responded by using visible Ukrainian flags on their vehicles. The picture has become more confused as both sides are using captured or abandoned equipment with Ukraine using captured Russian tanks.
