Direct proof of use
Air Force Special Operations Command documents the MC-130J Commando II's first deployment to Afghanistan in March 2013. AFSOC says the aircraft supported more than 400 missions, flew more than 2,000 hours, moved about 12,000 passengers, and carried 9.4 million pounds of cargo during that deployment.
An official 352nd Special Operations Wing account also documents a specific MC-130J combat-resupply mission in Helmand Province on Jan. 5, 2016. The account identifies the aircraft as an MC-130J Commando II and says the crew conducted a bundle drop for U.S. and coalition special operations forces while under small-arms and anti-aircraft fire.

Timeline
The public record ties the MC-130J's Afghanistan use to its early service life. The Air Force fact sheet says the Commando II entered deployment status in 2011, while AFSOC's final-delivery article places its first Afghanistan deployment in March 2013.
The most detailed public incident account is the Jan. 5, 2016 Helmand Province resupply. In that mission, the MC-130J crew was recalled after a long Afghanistan flight, loaded a supply bundle, and flew to a special operations team whose conventional resupply options had been exhausted. The 352nd Special Operations Wing account says the successful drop landed within 50 meters of the team.

Operational role
The documented Afghanistan role was special-operations mobility and sustainment rather than strike. The Air Force describes the MC-130J mission set as clandestine or low-visibility infiltration, exfiltration, airdrop or airland resupply, and aerial refueling for special operations helicopters and tiltrotor aircraft.
In Afghanistan, AFSOC's deployment summary records large-scale passenger and cargo movement, while the Helmand account shows the same aircraft type used for urgent battlefield resupply under fire. Stars and Stripes, citing Air Force award documents, reported that the Jan. 5, 2016 load included water, food, and ammunition for American and allied commandos facing Taliban fighters.
