WASHINGTON — The commandant of the Marine Corps has recommended that women be excluded from competing for certain front-line combat jobs, U.S. officials said Friday, as the Corps distanced itself from the other military services that are expected to allow women to serve in battlefield posts.

Officials said Marine Gen. Joseph Dunford submitted his recommendation to Navy Secretary Ray Mabus on Thursday. Mabus has made it clear he opposes the proposal and recommended that women be allowed to compete for any Navy or Marine Corps combat jobs.

The developments have raised questions about whether Mabus can veto the Marine Corps proposal to prohibit women from serving in certain infantry and reconnaissance positions. And it puts Dunford, who takes over next week as chairman of the Joint Chiefs of Staff, in the position of defending an exclusion in his own service that the Army, Navy, Air Force and U.S. Special Operations Command have suggested isn’t warranted in theirs.

Officials said Defense Secretary Ash Carter intends to review the Marine plan. The Marine Corps is part of the Navy, so Mabus is secretary of both services.

U.S. officials said they didn’t know the details of Dunford’s report, but suggested that the Marine Corps believes that mixed-gender units are not as capable as all-male units. So they concluded that allowing women to compete would make the Marine Corps a less efficient fighting machine.

The Marines in the past week have been publicly and privately laying the groundwork for the Corps to maintain the current rule that excludes women from infantry and some ground combat jobs.

The debate has triggered a call for Mabus’ resignation from a member of Congress who served in the Marines.

Officials say the Army, Navy and Air Force are expected to allow women to serve in all combat jobs and will not ask Carter for any exceptions. They say that Special Operations Command is also likely to allow women to compete for the most demanding military commando jobs – including the Navy SEALs – though with the knowledge that it may be years before women even try to enter those fields.

The officials spoke on condition of anonymity because they weren’t authorized to discuss the matter publicly.
