Enlisted

Staff Sergeant Pete Hill is sent home from Afghanistan for assaulting a superior and is forced to return to the US. Upon his return, he is made the platoon sergeant of a group of misfits at Florida-based Fort McGee that includes his two younger brothers, Derrick and Randy. Pete's sergeant major, Command Sergeant Major Cody, gives his platoon the task of finding a lost dog that belongs to the family of a deployed soldier. Pete's platoon is moments away from winning a war games exercise against a group of Italian troops when the dog is spotted in the battlefield, causing Pete to choose between winning the war games or rescuing the dog.

After Pete and Jill tie for the base marksmanship trophy, they embark on a series of additional competitions to try and break the tie. Meanwhile, Randy is the only member of his troop to fail the marksmanship test, so Derrick steps in with some unusual training methods to prepare his brother for a retest.

Randy wants Pete to move in with him and Derrick but Pete just wants to get away from everyone at the end of the day, so he buys a trailer away from the barracks. Meanwhile, Robinson and Park challenge Sgt. Perez's desire to be an enigma who keeps her work and private lives separate.
