ZB-53

The ZB-53 was a Czechoslovak machine gun. A versatile weapon, it was used both as a squad support weapon, as a mounted machine gun for tanks and other armoured vehicles, and on fixed positions inside Czechoslovak border fortifications. Adopted before the World War II by the armies of Czechoslovakia (as TK vz. 37) and Romania, it was also license-built in the United Kingdom as the Besa machine gun. Following the Munich Agreement the German Wehrmacht captured large quantities of the weapon and used it during the war under the designation of MG 37(t).

The weapon was a gas-operated, belt-fed, air-cooled machine gun that served both the infantry support and vehicle weapons roles. The machine gun was delivered in three variants: infantry machine gun (on heavy tripod), heavy bunker machine gun (with heavier barrel, marked "O") and for armoured vehicles (marked "ÚV"). It was designed to withstand five minutes of constant fire, after which time the barrel had to be changed due to wear. Although modern, the weapon was prone to jamming due to complicated rate of fire selection mechanism.
