JBSA joint, Total Forces practice sling loading skills Col. Kjäll Gopaul for 502nd Air Base Wing Public Affairs | January 8, 2021 Estimated reading time 9 minutes, 16 seconds. A joint Total Force team led by the 74th Aerial Port Squadron peers into a darkened landscape masked by a moonless evening sky in preparation for an ambitious helicopter sling load mission dubbed “Operation Nightstorm.” All of their other senses are heightened to compensate for the reduced visibility as Soldiers of Company C, 2nd Battalion, 149th Aviation Regiment “Alamo Dust off” descend toward the tactical landing zone in two UH-60L Black Hawks. U.S. Air Force Reserve Component Airmen assigned to the 74th Aerial Port Squadron, Texas Army National Guard Soldiers from the 2nd Company, 149st Aviation Regiment and 108th Aviation Regiment, and active-duty members from the Air Force Special Warfare Training Support Squadron participate in a helicopter rigging mission, Dec. 15, 2020, at Joint Base San Antonio-Chapman Annex, Texas.
