HISTORY
After the so-called Tito-Stalin split that took place in 1948, the new Yugoslav People’s Army (JNA- Jugoslovenska Narodna Armija) found itself in a very serious situation in terms of acquiring modern military equipment. Yugoslav newly found ally, USA, gave it some armored vehicles, including M4A3E4.
At the meeting of the Chief Military Expert Council held on the 4th of February 1956, it was decided to rearmed one Sherman (due to the obsolescence of M4 tanks) with the 122mm A-19 gun, and to test whether this modification was feasible and cost-effective at all. Thus, the SO-122 was born. The tank got new V-2/2R engine, 122mm A-19 gun and new smoke launchers.
