Development

After the unveiling of the lightweight M4 Carl Gustaf in October 2014, Saab began developing a concept dubbed the Ultra Light Missile, a guided round that could be fired from the recoilless rifle out to extended ranges. In November 2017, Saab and Raytheon teamed up to further cooperate on the project, and in September 2018 they were awarded a contract to answer a U.S. Special Operations Command (SOCOM) requirement for a precision guided Gustaf round. It was unveiled publicly as the Guided Carl Gustaf Munition (GCGM) in October 2018.New Long-Range, Guided 84mm Munition for Carl-Gustaf Headed for DoD Tests in Spring

. As it had been adapted to be launched from the AT4, the name was changed to the Guided Multipurpose Munition since it was no longer strictly related to the Carl Gustaf. Seven rounds were fired with live warheads, four from the Carl Gustaf and three from AT4s, against different types of targets such as a triple brick wall, a double-reinforced concrete wall and an up-armored vehicle at distances from 1,550 to 2,500 m.Guided Multipurpose Munition goes seven-for-seven from multiple launchers during live-fire demonstration
