Air Force Lt. Col. Robert Kline, 921st Contingency Response Squadron commander, test-drives a Polaris MRZR ATV after it was transported during a sling load training event as part of Green Flag Little Rock 21-01 at Little Rock Air Force Base, Arkansas, Oct. 19, 2020. The sling load training event tested the ability of a UH-60 black hawk to effectively transport a Polaris MRZR ATV, a first in Air Mobility Command history. This capability will help contingency response teams react faster with lighter equipment. (U.S. Air Force photo by Airman 1st Class Isaiah Miller)
