The 3.7 cm ÚV vz. 38 (Czech: útočná vozba), manufacturer's designation Škoda A7, was a 37 mm tank gun designed by the Skoda Works in Czechoslovakia prior to World War II.

The gun was the primary armament of the Czech LT vz. 38 light tank, known in German service as the Panzer 38(t).

The primary user of the A7 was the Wehrmacht during World War II where the weapon went by the name 3.7 cm Kampfwagenkanone 38(t).

Performance

In German service, in addition to conventional high explosive ammunition, the weapon fired two anti-tank rounds. The primary round the Panzergranate Pzgr.(t) umg. armor-piercing capped ballistic cap (APCBC), was ineffective at 2,000 m (2,200 yd) and beyond. The rarer tungsten Panzergranate 40 armor-piercing composite rigid (APCR), was ineffective at 1,000 m (1,100 yd) and beyond.
