Studies and Observation Group (SOG) during the
Vietnam War. The project focused on placement of
exploding cartridges into supplies used by communist combat forces in southeast Asia. United States technicians assembled 11,565
7.62×39mm cartridges for
AK-47 rifles, 556

machine gun cartridges, and 1,968 82mm
Type 67 mortar shells to detonate in the weapon when firing was attempted.
