Members of the 74th Expeditionary Fighter Squadron were accustomed to the conflict conditions of Afghanistan, in which airstrikes aren't often carried out in close quarters.
But one A-10 Thunderbolt II unit summoned into the dense, urban environment of Raqqa, Syria, where Islamic State fighters and snipers hid within buildings, found itself testing new ways to support U.S.-backed militia on the ground, contributing to the city's liberation in late 2017.
The A-10 is a flying death machine, a plane built around a cannon that is capable of firing 4,200 rounds per minute and eliminating anything in its path, but this fearsome gunship's days are numbered.
Some U.S. Air Force pilots are currently transitioning to flying other aircraft, like the new F-35A Lightning II Joint Strike Fighters that are supposed to replace many of the A-10s for ground attack missions.
Here's what one pilot had to say about the shift during the Air Force's Red Flag air combat exercises.
