In May 2017 it was decided to give the Bundeswehr Leopard 2 tank an upgrade in the form of the Leopard 2 A7V; building upon the A7 variant, the A7V has additional hull front armor to increase its survivability, with new running gear to compensate for the extra weight. Its L/50 120mm gun is a carryover from the A6 variant which - when using the latest ammunition - can take on enemy armor up to five kilometres away. Other design evolutions include a sight device to amplify vision in poor visibility, new tracks and a new turret rear basket. 104 existing tanks are to be upgraded to A7V spec, and units began receiving them in September 2021.
