Under Kuwaitkrigen begir en gruppe marinesoldater seg ut i den ubarmhjertige ørkenheten for å utføre et oppdrag som skarpskyttere på jakt etter en fiende de ikke ser i et land de ikke kjenner av en grunn de ikke forstår. Men de er alle stolte soldater født inn i en tradisjon av frivillig verving og de ville aldri komme på tanken å gi opp oppgaven av en så enkel grunn.

Battle-scarred and disillusioned by the war, Corporal Chris Merrimette is put in charge of a unit whose next mission is to resupply a remote outpost on the edge of Taliban-controlled territory. While driving through the hostile Helmand province, a Navy SEAL flags down their convoy and enlists the unit on an operation of international importance: they must help an Afghan woman famous for her defiance of the Taliban escape the country. Without tanks or air support, Merrimette and his team will need all the courage and firepower they can muster to fight their way across the war-torn country and shepherd the woman to safety.

Corporal Evan Albright joined the elite Marine Corps Security Guards to save the world and see some action-not necessarily in that order. But his first assignment, protecting a U. S. Embassy in a seemingly safe Middle Eastern capitol, relegates his unit to wrangling "gate groupies" protesting outside the compound and honing their marksmanship by playing video games. So Albright and his team are caught off guard when well-armed and well-trained militants launch a surprise attack aimed at killing an informant in the embassy. Heavily out-gunned, they will have to muster all the courage and fire power they can as their once routine assignment spirals into all-out war.
