Women Marines can volunteer for officer's infantry basic school

NY Times:

Training Course Opens to Female Marines

Beginning in September, female officer volunteers will participate in the Marine Corps’ Infantry Officer Course, often called the most grueling school by its instructors.

It is a very challenging course that requires top conditioning.  From the obstacle course to the confidence course it requires both upper and lower body strength.  The course also develops leadership skills under stress.  It features 20 mile hikes and live fire drills.  When I went through it, most days began with a three mile run in combat boots.  Some exercises included longer runs in full battle rattle.
