Direct proof of use
The HMMWV was documented in the 2001 War in Afghanistan through official U.S. military reporting on Afghan National Army training, U.S. patrol operations, and Afghan convoy use. In June 2008, DVIDS reported that Afghan soldiers were training on up-armored HMMWVs at the Kabul Military Training Center and that nearly 5,000 U.S.-supplied Humvees were to be delivered to the Afghan National Army.
U.S. and coalition forces also used Humvees directly in Afghanistan. A May 2010 DVIDS report from Kandahar City said the 97th Military Police Battalion had used MRAPs and Humvees to patrol the city before receiving M-ATVs, while earlier DVIDS reporting from Gardez described a U.S. convoy in Paktya Province that included Humvees and a disabled Humvee after an improvised explosive device strike.

Timeline
The available official reporting shows the HMMWV moving from coalition tactical use into Afghan security-force fielding during the middle years of the war. In 2008, Afghan soldiers were being trained to maintain and operate up-armored Humvees in Kabul, with the M1151 described as the training and battlefield model.
By 2009, Afghan National Army soldiers and Afghan border police were receiving M1151 Humvee familiarization and driving instruction at Forward Operating Base Curry in Paktika Province. In 2012, Afghan National Army instructors at Camp Hero were independently teaching an up-armored Humvee course, showing that the vehicle had become part of Afghan security-force training infrastructure.

Narrative
In Afghanistan, the HMMWV functioned mainly as a light tactical mobility and force-protection vehicle rather than as a single fixed weapons system. DVIDS reporting described up-armored Humvees in Afghan driver training, Kandahar patrol use by U.S. military police, and convoy operations exposed to roadside bombs.
The Afghan fielding record is especially clear. The 2008 Kabul training report said HMMWVs were expected to become the Afghan National Army's vehicle of choice on the battlefield after qualification, and the 2009 Paktika report said the 3-509th Parachute Infantry Regiment was lending Humvees to Afghan forces for missions to assist operational security. The 2012 Camp Hero report then documented Afghan instructors running their own up-armored Humvee course for Afghan soldiers, recruits, and some police.
Later Afghan use continued into the final phase of the war. In June 2020, DVIDS reported an Afghan Border Forces convoy between Jowzjan and Balkh in which the second Humvee was destroyed by an improvised explosive device, killing two soldiers and wounding Lt. Col. Hamid Saifi. That report supports continued Afghan government use of Humvees in convoy operations well after coalition combat forces had shifted to a train, advise, and assist role.
