Two students of the Fort Bliss Air Assault Training

Two students of the Fort Bliss Air Assault Training Program prepare to rappel from a UH-60 Black Hawk helicopter of the 3rd Battalion, 501st Aviation Regiment, Combat Aviation Brigade, 1st Armored Division during a rappel training exercise at Fort Bliss, Texas, April 21, 2015. The rappel training is one of the final tests for the air-assault students, and the Apocalypse assault helicopter battalion helps familiarize the trainees – many of whom have never flown on a helicopter before – with the Black Hawk.
