2S3M
The SO-152 (Russian: СО-152), usually known by its GRAU designation 2S3 (Russian: 2С3),
is a Soviet 152.4 mm self-propelled gun developed in 1968, as a response to the American 155 mm M109 howitzer.
Development began in 1967, according to the Resolution of the Council of Ministers of the Soviet Union from July 4, 1967.
In 1968, the SO-152 was completed and in 1971 entered service.
The fighting vehicle also received the added designation Akatsiya (Акация), which is Russian for Acacia.
The 2S3 production line continued to operate until the collapse of the Soviet Union at the end of 1991.
During the 23 years, the Soviet Union produced more than 4,000 2S3 and related derivative vehicles.
