Afghan Air Force MD-530 Jengi helicopters were documented carrying two HMP 400 .50-caliber machine-gun pods while operating in Afghanistan. U.S. Air Forces Central described the MD-530 as a close-air-attack aircraft and reported that Afghan crews used the armed helicopters to support Afghan National Defense and Security Forces with convoy escort, aerial reconnaissance, armed overwatch, and close air support.
On 2015-09-27, Afghan MD-530s and Mi-17s departed Hamid Karzai International Airport for operations in Helmand Province. The same official reporting described the deployment as participation in combat missions in Afghanistan's southwest zone and stated that each MD-530 carried two HMP 400 .50-caliber pods.

Timeline
The first six armed MD-530 helicopters were delivered to the Afghan Air Force in March 2015, and U.S. Air Forces Central later described Afghan crews returning from their first combat mission after the January 2015 reduction in coalition airpower.
By late September 2015, the Afghan Air Force was deploying MD-530s from Kabul to Helmand Province for expeditionary combat operations. A DVIDS image from 2015-09-27 shows Afghan pilots preparing for an all-Afghan crew combat mission from Hamid Karzai International Airport, while the associated story places the MD-530s in the Helmand deployment.

Narrative
In Afghan government service, the 12.7 mm gun pod appeared as part of the MD-530F Cayuse Warrior light-attack helicopter package rather than as a stand-alone ground weapon. The pod gave Afghan pilots a fixed-forward .50-caliber armament option for missions flown in support of ANDSF units.
The documented roles were tactical and local: close air attack, convoy escort, armed overwatch, reconnaissance, security, and aerial interdiction. Official reporting does not identify specific targets struck by individual pods in the cited missions, so the source-backed claim is that the pods equipped Afghan MD-530s fielded for those combat-support missions in Afghanistan.
FN Herstal identifies the HMP400 family as a self-contained airborne pod built around the FN M3P .50-caliber machine gun, with a 400-round ammunition box in the HMP400 configuration. MD Helicopters later listed FN Herstal HMP 400 .50-caliber machine-gun pods among the Afghan Air Force MD-530F Cayuse Warrior equipment.
