The British-developed Marksman turret was originally sold to Finland and mounted on T-55AM chassis. This was designated ItPsV 90. These were put into storage in 2010, but all seven turrets have now been mounted on former Leopard 2A4FIN hulls. After two years of trials and development, they entered service in 2017.
