The guerrillas' AKM rifles and such variants were highly thought of by many Portuguese soldiers, as they were more mobile than the m/961 (G3), while permitting the user to deliver a heavy volume of automatic fire at the closer ranges typically encountered in bush warfare. The AKM's ammunition load was also lighter. The average Angolan or Mozambican rebel could easily transport 150 7.62×39mm cartridges (five 30-round magazines) on his person during bush operations, compared to 100 7.62×51mm rounds (five 20-round magazines) typically carried by a Portuguese infantryman on patrol. Though a common misconception holds that Portuguese soldiers used captured AKM type weapons, this was only true of a few elite units for special missions. Like U.S. forces in Vietnam, ammunition resupply difficulties and the obvious danger of being mistaken for a guerrilla when firing an enemy weapon generally precluded their use.
