The 2S7M 203mm Self Propelled Howitzer is an updated version of 2S7 Pion which refers to a Soviet-made self-propelled 203mm heavy artillery system. In the West, it has been attributed to the M-1975 as this is the year when the system was first observed. The former Soviet ground forces began receiving the 203 mm Model 1975 (M-1975) self-propelled gun in 1975.
