The only two women to participate in the Marine Corps Infantry Officer Course (IOC) failed ongoing tests to determine which infantry positions should be available to women, according to the Marine Corps Times:

The women failed the introductory Combat Endurance Test, a punishing test of physical strength and endurance, officials at Marine Corps headquarters said Tuesday. The latest class began March 28 at Marine Corps Base Quantico, Va., with 110 lieutenants participating. Ninety-six men passed the initial endurance test. Twelve men and two women — the only female Marines taking part — failed.

The two women both volunteered to participate in the IOC. Two other women had previously volunteered in September but also failed.
