   The Marksman self-propelled anti-aircraft gun was developed by Marconi. This British company had a history of radar development. The Marksman is comparable with the German Gepard SPAAG. The only operator of this SPAAG is Finnish Army, which ordered 7 units in 1990, locally designated as the ItPsV 90.

   The Marksman is intended to provide low-level air defense for armored battalions. Vehicle is primarily used against helicopters, low-flying aircraft and unmanned aerial vehicles, however it can be also successfully used as a fire support vehicle.

   The Marksman is armed with two 35-mm Oerlikon KDA automatic cannons. A total of 460 fragmentation rounds and 40 armor-piercing rounds are carried.

   This SPAAG is fitted with British Marconi surveillance and tracking radar, which has a range of 12 km in search mode and 10 km tracking range. Laser rangefinder has a range of 8 km. The Marksman is also fitted with British fire control system.

   Vehicle has a crew of three, including commander, gunner and driver.

   The Finnish ItPsV 90 is based on a modified Polish T-55AM medium tank chassis. Vehicle is powered by a V-55 diesel engine, developing 620 hp. It is worth mentioning that the AM has a more powerful engine than a regular T-55. The Marksman turret can be adapted to many ageing tank chassis, such as the Centurion, Chieftain, Leopard 1, making them capable low-level anti-aircraft weapon systems.
