Abstract: A combat vehicle, in particular a combat tank, with a weapon mounted outside its longitudinal middle axis, that is mounted on a vertical axis rotatable ring mount linked by rotational rings to the hull of the vehicle. Within the rotational rings is a controllable coupling with plural coupling elements distributed on the circumference of the rotational ring. The coupling elements are, in a disengaged position, freely rotable in the ring mount and in an engaged position are unrotatable in the ring mount linked to the hull. During firing of the weapon, the coupling elements are controlled such that after the exit of the projectile from the weapon barrel but before the ending of the free weapon barrel recoil, the couplings are moved to an engaged position.
