A soldier from 3rd Battalion, 320th Field Artillery Regiment, 101st Airborne Division Artillery Brigade, ties down parts on a M777 howitzer during a platoon-level validation live-fire to prepare it for sling load on a CH-47 Chinook helicopter, Jan. 31, 2018, at a Fort Campbell, Kentucky. This is a bi-annual progressive type of training that prepares soldiers for air assault gun raid by transporting soldiers and howitzers from one training area to another, then the soldiers are given a fire mission and a time in which they must be ready to fire.
