Three Finnish Itpsv 57s lined up for anti-air duties as a part of Armoured Brigade’s annual exercise. They are used to keep battalions’ equipment safe from distrubing factors coming from above. Itpsv 57s (aka ZSU-57-2) are built on shortened T-54 chassis with only four road wheel pairs. Vehicles are armed with two 57mm guns with practical rate of fire around 70 rounds/minute from both barrels. Maximum engagement range is between 3 – 4 kilometers. Nowadays these vehicles are consired almost obsolete and will face retirement or heavy modernisation in near future.
