The Model 1968 recoilless gun is a 105-mm antitank weapon developed and employed by Argentina.

In the late 1960s or early 1970s, the Argentine military attempted to use it as a self-propelled gun or tank destroyer.

At least two prototypes (one being either an IHC M5 or M9 half-track and the other a Bren carrier) were fitted with a six-cannon mount each, similar to that of the US-made M50 Ontos.

Between 1977 and 1978, on the eve of Operation Soberanía, many carriers and half-tracks were converted to self-propelled guns by having a single Model 1968 mounted on them.

[citation needed] The Model 1968 was fielded by the Argentine Army during the Falklands War.
