Amid the Department of Defense's historic change to open all combat jobs to women, the Marine Corps accepted the first female applicants to the sister service branches' special operations command (MARSOC), Military.com reports.

"We've actively identified all the females in the Marine Corps writ large who meet all the prerequisites just like with our normal screening teams," MARSOC Commander Major General Joseph Osterman told Military.com.

"We've notified or contacted every one of them and let them know, 'it's open, you're eligible.'"

"I totally support women in combat, women being eligible to compete for any position in the military," former Defense Secretary Gates told Business Insider.

"But I would agree with military leaders there can be no lowering of the standards of the requirements to perform specific jobs, lowering standards will put lives at risk," Gates added.

According to Osterman the standards for MARSOC qualification will not be changed. "Our standards are as they've always been and we're not changing them," Osterman told Military.com.

MARSOC candidates arrive for the training in the best shape of their lives and survive on a meal a day and just a few hours of sleep — all the while completing some of the toughest military training in the world.

According to Osterman, approximately 40% of the Marines who enter MARSOC's notoriously grueling training pipeline become US Special Operations Command (USSOCOM) operators.

The training for MARSOC begins after a three-week initial assessment that tests physical fitness and a range of other general technical skills.

Phase 1 is a 21-day course at Camp Lejeune, North Carolina, that screens for "enhance physical ability, confidence, situational awareness, and acclimatization," according to the Marine Corps.

During the first phase, candidates must complete a brutal 8-mile rucksack run, swim 300-meters in cammies, tread water for 11 minutes, complete a second ruck run that's 12-miles long in under 3 hours while carrying 45 pounds.

Then it's on to Phase 2, and then a final nine-month 'individual training course,' which includes close urban combat, recon training and SERE school — the training course that teaches elite soldiers how to survive if they are captured and tortured.
