The Main Ground Combat System (MGCS) is an ambitious German-French armaments project. MGCS is intended to replace the Leopard-2 in the future.

The tank based on the MGCS concept boasts a low combat weight and high mobility. The future tank does not appear as a single vehicle, but as part of a group whose vehicles share the same platform. It is expected that the future combat platform will have a weight limit of less than 50 tons. This would make him significantly lighter than his potential opponents.
