363rd Training Squadron armament apprentice course students are briefed by instructor Tech. Sgt. Stephen Jervis before starting their day at Sheppard Air Force Base, Texas, Feb. 5, 2019. Sheppard is known to have weird weather patterns, one day it may be high 70s and just the next day it could drop to the 40s. It also gets really foggy, but that doesn't stop the training at Sheppard as it actually helps the students practice as if in different locations.
