The FN MAG is FN Herstal's Belgian 7.62x51mm NATO belt-fed general-purpose machine gun family, fielded from infantry bipods, tripods, vehicles, aircraft, ships, and boats. The catalog record connects the MAG and its M240/L7A2/MAG 58 designations to directly sourced conflict evidence: surrendered Boko Haram-held stocks in Nigeria, coalition base-defense training during Operation Inherent Resolve, and Afghan special-operations weapons training during the War in Afghanistan.
Role in Conflicts
U.S. Army and DVIDS reporting documented M240B and FN Mag-family guns used by coalition personnel during weapons familiarization and base-defense live-fire training at Al Asad Air Base and elsewhere in the OIR theater.
A 2018 DVIDS report from near Kabul said Afghan National Army Special Operations Command soldiers received advanced weapons training on squad-level weapons including the M240 general-purpose machine gun during the Resolute Support phase of the 2001 War in Afghanistan.
