U.S. Air Force Senior Airman Nathaniel Mitchell, right, 423rd Security Forces Squadron (SFS) combat arms training and maintenance instructor, gives instructions to Airman 1st Class Shawn Morris-Jackson, 423rd SFS armory patrolman, during a M18 handgun qualification course at RAF Molesworth, England, July 28, 2020. During the course, Airmen from the 423rd SFS became familiar with the M18 and learned about its various functions and overall benefits such as improved ergonomics, target acquisition, reliability and durability to increase shooter lethality. The M18 Sig Sauer Modular Handgun System will be replacing the M9 Beretta which has been in use for over 30 years. (U.S. Air Force photo by Senior Airman Eugene Oliver)
