Pfc. Christina Fuentes Montenegro prepares to hike

Pfc. Christina Fuentes Montenegro prepares to hike to her platoon's defensive position during patrol week of Infantry Training Battalion near Camp Geiger, N.C. on Oct. 31, 2013. Fuentes Montenegro is one of the first three females to ever graduate from Infantry Training Battalion. Patrol week is a five-day training event that teaches infantry students basic offensive, defensive and patrolling techniques. Delta Company is the first infantry training company to fully integrate female Marines into an entire training cycle. This and future companies will evaluate the performance of the female Marines as part of ongoing research into opening combat-related job fields to women. (U.S. Marine Corps photo by Sgt. Tyler L.
