The old saying "every marine is a rifleman" still holds true in the Alliance. Every marine enlistee, from clerk to sniper, goes through a period of infantry training. As a result, the 103rd Marine Division is Earth's largest collection of Special Forces soldiers. Officers from notable battles such as the Skyllian Blitz and the First Contact War, run harsh training exercises in a variety environments, insisting the marines be prepared to storm any beach, on any planet. This training has been useful in the Reaper War, as the 103rd can be fighting in an arctic desert one week, crawling through jungles the next.
