Five days into the first U.S. Marine Corps Forces Special Operations Command assessment and selection course to admit women, one female Marine has washed out and one remains.

Capt. Nicholas Mannweiler, a spokesman for the command, told Military.com that two women, a staff sergeant and a corporal checked in Aug. 9 at the command's headquarters near Camp Lejeune, North Carolina, and began the first 19-day phase of assessment and selection on Aug. 11.

The staff sergeant washed out of the course the following day during a timed ruck march, Mannweiler said. The news was first reported by Marine Corps Times.

Both the corporal and the staff sergeant came from administrative military occupational specialties, Mannweiler said. He did not disclose their identities or ages.

Mannweiler said he couldn't say how many started the A&S class for operational security reasons, but noted that 32 Marines, including the female staff sergeant, have departed the course so far.

The first phase of assessment and selection tests physical fitness and a range of aptitudes to ensure Marines are physically and mentally prepared for what will be 10 months of intensive follow-on training to become Marine Raiders. Alongside physical training, Marines receive classroom instruction in land navigation skills, MARSOC and special operations history, and nutrition and fitness.

In January, Maj. Gen. Joseph Osterman, then the commander of MARSOC, called A&S Phase 1 a holistic profile for the Marines who qualify to enter the training pipeline.

Military.com broke the news in March that a female staff sergeant had been accepted for A&S, just months after a mandate from Defense Secretary Ash Carter had required all military services to open special operations jobs and other previously closed fields to women.

Osterman said then that MARSOC leadership had leaned into the new reality, reaching out to all eligible female Marines through the command's recruiting arm to give them the opportunity to apply.

The current A&S phase is set to conclude Aug. 22. If the female corporal in A&S can make it through this phase, she will enter a second, more secretive three-week A&S phase. Following that is MARSOC's individual training course, which covers survival, evasion, resistance and escape [SERE], special reconnaissance, close urban combat, irregular warfare and more over the course of nine intensive months.

Those who wash out of A&S have up to two chances to re-enter the pipeline, Mannweiler said, as long as they have enough time left on their contracts and until their next promotion, and the command has enough boat spaces to accommodate them.

While MARSOC recruiters have received interest from other female Marines, the command is not currently processing any other applications from women, Mannweiler said.
