75mm recoilless rifle (CHICOM Type 52/56). Particularly favoured by the NVA and VC, the Type 52 combined firepower with light weight and could fire both PRC (Chicom) and US ammunition. This weapon was frequently used in attacks on fire bases and other strong-points. This was a breech-loading, portable weapon, designed to be fired from a machine gun tripod. The barrel and breech of the 52/56 weapon were copied from those of the US 3.5inch M20 rocket launcher.
