SFS practice response
PETERSON AIR FORCE BASE, Colo. – A 721st Security Forces Squadron member, playing the role of the “enemy,” seeks to take out the forces advancing on him during an annual training mission at the 21st Security Forces Training Complex, June 16. 721st SFS members conducted an active shooter, live-fire training using non-lethal training ammunition, which allows for the most realistic force-on-force training.
