Marines are shown facing down the insurgents, who fight a guerrilla war from the shadows and use their local knowledge to stage ambushes. Combining the different specialities contained within the four-man Fireteam, Marines sweep through compounds and towns, engaging enemies at close quarters and long range. Reflecting their role in a broader conflict as part of a large expeditionary force, they are shown in action alongside artillery, armor, air-support and additional infantry fireteams.
