3 x T-55 Marksman Anti-aircraft Tanks
 
To replace the aging ZSU-57-2 AA tanks, the Finns fitted the British Marksman turret to the T-55 tank hull. The Marksman turret has proved to be a very accurate anti-aircraft artillery system, having a documented hit percentage of 52.44%.
 
It has a modern Marconi Series 400 anti-aircraft radar system and is armed with two Swiss Oerlikon 35mm anti-aircraft autocannons, giving it similar performance to the West German Gepard.
