Lawmakers have ordered a briefing with those involved with the Marine Corps study that claimed all-male units outperform units including women.

A recent Marine Corps study stating all-male combat units perform better than combats including women, has sparked debate and a lawmaker briefing.

This news comes just as the Pentagon is preparing to open all combat jobs to women. Representative Susan Davis said in a statement:

"We will be gathering folks together who have been part of that study and having a briefing on it soon.”

The Marine study pointed out females in the mixed-gender unit were slower, less accurate in their shooting and more easily injured than the all-male group.

Founder and program director for “Soldier’s Heart” who advocate for women in combat told USA Today the study published in early September doesn’t question the military culture itself— suggesting men might not perform well with women.  She also added women have to put up with sexual harassment by fellow troops, denying the credibility of where the study came from.

In a similar point, representative Martha McSally said lawmakers have not seen the study, but she has concerns the study is biased as female marines felt they were thrown under the bus, according to The Hill.

The military services have until the end of September to request an exception to the order on whether any combat jobs should remain closed to women.
