Last year, a gunship crew from an Air Force Special Operations Command (AFSOC) squadron helped turned the tide in a fierce engagement against ISIS fighters in Afghanistan.

The nine-hour operation took place last April in Nangarhar Province. An AC-130U aircraft from the 4th Special Operations Squadron was proving overhead support to a Special Forces assault force that was going after an ISIS mountain redoubt.

Major Jeffrey Wright, a Special Tactics Officer with the 24th Special Operations Wing, said in an interview with DVIDs that “it would be inaccurate to describe this target as a village. Rather, this was a military installation literally dug into the side of the mountains, with a single path through which friendly forces could assault. The enemy consolidated their forces here in a warren of interconnected command and control nodes, operations centers, staging areas, and ‘on-base housing’ for ISIS-K leaders. This was no low-level commander and his men: this place was ‘ISIS-K’s Pentagon.’”

An AC-130U and its impressive arsenal.

Although the assaulters had the numerical advantage over the ISIS fighters, they had the terrain disadvantage. Alongside operations in an urban setting, mountain warfare presents one of the toughest combat environments. The enemy often, but not always, occupies the vital high ground, thereby having an added advantage to that of being the defender.

At one point, the assault stalled as wounded pilled in. At that point, a Special Warfare operator requested close air support (CAS) from an orbiting AC-130U gunship (callsign “Spooky 41”). Within seconds, effective fire began raining down on the enemy positions, which were precariously close to the American element. As Major Wright mentions in his account, the ISIS fighters thought that their close proximity to the American commandos would automatically negate any sort of air support for fear of a blue-on-blue incident (friendly fire). This tactic is as old as gunpowder and has been used to great effect by forces with firepower inferiority, for instance, the North Koreans or the North Vietnamese in the Korean and Vietnam wars respectively.

Spooky 41’s accurate fire enabled the ground force to call in a MEDEVAC to evacuate the wounded. Three times American helicopters braved the situation and hoisted the wounded. In the meantime, Spooky 41 provided such effective suppressing fire that the ISIS fighters weren’t able to hit the vulnerable helicopters. Without Spooky 41, the ISIS stronghold would have claimed many dead or wounded before it fell.
