[3] In 2015 work began to install the system on the Leopard 2A4 chassis in order to make up for the loss of mobile anti-aircraft coverage when the Marksman was originally retired.
[5][needs update] Finland has seven ItPsv 90 Marksman anti-aircraft systems, providing low-level air-defense for tank battalions.
The ItPsv 90 Marksman is primarily meant to fight helicopters, low-flying aircraft and unmanned aerial vehicles (UAVs).
The armament consists of two Swiss 35 mm Oerlikon anti-aircraft guns, with a rate of fire of 18 rounds per second.
The Leopard 2 chassis is also larger, thus providing a more stable firing platform for the Marksman turret to operate from.
In 1994, Marconi and South African Denel group announced plans to install a Marksman turret on a G6 howitzer chassis;[7] Marconi also offered conversions for existing users of T-54/55, Type 59,[8] Centurion, M48 Patton, Vickers,[9] Chieftain, Challenger 1 and Leopard 1 tanks.
