The four squads assemble on the grounds of Camp Windstorm for briefing. Commander Rudy Boesch addresses the men, and announces the next competition will be between Alpha and Charlie.

Alpha and Charlie face off in The Grid Training Exercise. Each team member is issued a helmet and a pugil stick. The two squads proceed on to an open grid in a dock with 52° water. Each team tries to knock all of the members of the other team off the grid and into the water. The team with the last man standing wins 75 extra points towards mission. Alpha Squad wins this Training Exercise.

After getting a blow on his nose during the training exercise, Charlie Squad's Young proceeds to the medical tent. Camp's Medic Heather Cunningham treated Young's injured nose. Later, Cunningham discovers her duties as Camp Medic also include being the camp's barber, as Commander Boesch stops by for a haircut.

Like Bravo and Delta Squads in Evolution Three, Alpha and Chalie Squads will take on the Prisoner Rescue mission.
