Goslin said the eight-person teams are allowed one alternate team member and a noncompeting team captain. Additionally, teams are primarily enlisted, although each team is allowed one competing officer. He said competitors may participate in Peacekeeper Challenge for two consecutive years, then must skip a year before competing again. He said this year's scenarios are driven by situations encountered by security police deployed to various hot-spots around the world. Peacekeeper Challenge team events include fitness challenge, combat rifle, defender challenge, handgun and machine gun.
Individual events are grenade launcher and the chief's challenge.
Upper and lower body strength, agility, balance and running endurance of five team members are the objective of the physical fitness and chief's challenge events. Marksmanship skills within set time parameters under simulated combat conditions are measured during the combat rifle event. During the defender challenge competition, an eight-person team performs a base defense wartime or contingency operation mission. During the handgun competition, a four-person team fires a course that simulates law enforcement and combat employment situations. The machine gun competition allows a two-person machine gun crew to be tested for accuracy at range distances with different target configurations against the clock.
