The 76-mm regimental gun M1943 (OB-25) (Russian: 76-мм полковая пушка обр. 1943 г. (ОБ-25)) was a Soviet infantry support gun developed in 1943 by M. Yu. Tsiryulnikov at the ordnance plant in Motovilikha. The gun used a modernized barrel from the 76 mm regimental gun M1927 and the carriage from the 45 mm anti-tank gun M1942 (M-42). The gun was intended for destruction of light field fortifications and openly placed personnel by direct fire. HEAT shells gave it limited anti-armor capabilities. 76.2-mm regimental guns M1943 completely replaced M1927 guns in production that year and were built until the end of the German-Soviet War. Soon after the end of the war the production ceased due to insufficient range and muzzle velocity. ==Ammunition== *Ammunition types: * *Fragmentation-HE: OF-350. * *Fragmentation: O-350A. * *HEAT: BP-350M. *Projectile weight: * *OF-350: 6.2 kg. *Muzzle velocity: * *OF-350, O-350A: 262 m/s. * *BP-350M: 311 m/s. *Effective range: * *OF-350, O-350A: 4,200 m. * *BP-350M: 1,000 m. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「76 mm regimental gun M1943」の詳細全文を読む スポンサード リンク
