Battlefront has another of their features for Tour of Duty up. This one’s for the ZSU-57-2 Anti-air company.
From the website:
ZSU-57-2 Anti-air Company (VPABX05) includes four ZSU-57-2 Anti-aircraft tanks, four PAVN head sprues & one PAVN tank decal sheet.
The ZSU-57-2 was a Soviet built self-propelled anti-aircraft gun that first came into service with the Red Army in 1955. The acronym ZSU stands for Zenitnaya Samokhodnaya Ustanovka, which when translated means anti-aircraft self-propelled mount; 57 designates the calibre of the weapons and 2 states the number of gun barrels.
