A mortar mount adapter is configured to fit in a towing hitch system mounted on a land vehicle. The towing hitch system absorbs and disperses recoil force from the mortar. The adapter is disposed in one of a trailer hitch receiver, a gooseneck hitch socket, and a fifth wheel hitch. The adapter includes a socket for the ball of a mortar tube and a shank extending from the socket wherein the socket and the shank are symmetrical about the central longitudinal axis of the adapter.
