Direct proof of use
Official U.S. reporting documents M16 rifles in the 2001 War in Afghanistan on both U.S. and Afghan government force lines. DVIDS reported that coalition forces were issuing M-16 rifles to the Afghan National Army's 203rd Thunder Corps in February 2009, and a Kabul Military Training Center report the next month described Afghan recruits receiving new M-16 rifles for field training.
The record also includes direct operational use. In July 2014, Marine Corps reporting from Gereshk, Helmand Province, said riflemen with M16A4 service rifles returned fire during a Taliban engagement. For Afghan forces, a 2013 Kapisa Province account described an Afghan National Army patrol vehicle damaged by an improvised explosive device with an M-16 rifle inside, followed by U.S. Army repair training intended to return ANA M-16 rifles to service.

Timeline
The documented Afghan transition began before the catalog's post-2015 focus period. In February and March 2009, U.S. and coalition reporting described M-16 issue and training at Bagram Air Field and the Kabul Military Training Center as Afghan units moved from Soviet-pattern rifles toward NATO-standard weapons.
A November 2009 Kunar Province report placed Afghan soldiers on a live-fire training range with M-16 rifles and M-249 machine guns, with trainers saying the weapons would help ANA patrols in the Pech River Valley. GAO later summarized the broader equipment program, reporting in 2017 that NATO-standard weapons including M16 rifles had become basic issue for the Afghan National Army in 2010 and that the Afghan National Police were still transitioning to NATO-standard weapons as of May 2017.

Narrative
The M16's Afghanistan role was mainly a standard infantry-rifle and security-force-assistance role. U.S. forces used M16A4 service rifles in infantry operations, while Afghan government forces received M16 rifles as part of a coalition-backed effort to modernize the Afghan National Army and align its small arms with NATO-standard ammunition and training.
The Afghan fielding record separates transfer and training from battlefield use. DVIDS accounts show M-16 issue, familiarization, live-fire training, and repair support for ANA units. The 2013 Kapisa report is an operational-context example: an ANA patrol vehicle hit an IED and an M-16 rifle in the vehicle was damaged, prompting small-arms repair instruction so Afghan soldiers could keep rifles serviceable.
GAO's 2017 equipment review places those incidents inside the larger U.S.-funded ANDSF equipment program. GAO reported nearly 600,000 U.S.-funded weapons for Afghan security forces through fiscal year 2016 and stated, citing DOD documentation, that M16 rifles, M4 carbines, and M203 grenade launchers became basic issue for the ANA in 2010.
