Force Recon (S02E11)

Harm goes undercover as a Marine gunnery sergeant to assist Mac with her inquiry into dubious Marine training practices, only to find himself caught in perilous situations. During his time undercover, he discovers that the relentless Capt. Koonan, who oversees Force Recon training, deliberately complicates drills to condition the Marines to respond swiftly to unexpected challenges in combat. While this approach is meant to strengthen their resilience and improve survival rates, it takes a dangerous turn during Harm's mission, trapping five Marines in a precarious training scenario. Now, Harm must find a way to rescue the trainees—and himself—before it’s too late.
