From corpsman to infantryman, submariner to special operator, Navy Secretary Ray Mabus has insisted that every Navy and Marine Corps job be opened to qualified women. It allows women to compete on a more equal footing with men, it recruits a much larger portion of the nation's workforce and graduates, and he's argued, it's only fair.
Many of these moves have come over strenuous and strident opposition.
The first was the undersea fleet. Mabus came into office in 2009 and aggressively pushed to open it to women.
"I believe women should have every opportunity to serve at sea, and that includes aboard submarines," Mabus told Navy Times at the time. The proposal had objections. Berthing changes would be expensive and take some time. Privacy issues would be difficult in a sub's cramped spaces. Submarine wives were among the biggest opponents.
"There is no way they will be able to stop fraternization," one wife told Navy Times in 2009. "I will never be at ease."
The integration effort moved ahead and the first women officers reported to the sub fleet in late 2011. The first enlisted women are set to report to the force this year.
In an interview with NPR, he decried the study as flawed.
"It started out with a fairly large component of the men thinking 'this is not a good idea,' and 'women will never be able to do this,' " he told host David Greene. "When you start out with that mindset, you're almost presupposing the outcome."
Many Marines took issue with Mabus' comments. An influential sergeant major who oversaw the study said Mabus was "way off base" and a retired 3-star wrote an op-ed criticizing the move.
In the end, Mabus' decision prevailed, and on Dec. 3, Defense Secretary Ash Carter announced that all four services would be opening every job specialty to women: No exceptions.
"The cadets marched out in absolutely gender-neutral uniforms. Mids marched out and you could tell what the women wore by their covers," he recalled. "If we ask another group to wear a different uniform, can you imagine the trouble we'd get in?"
For instance, men and women with the New York Police Department wear the same style of dress uniform.
Mabus is pushing to outfit men and women in the same style uniforms and symbolically break down barriers that have stood for decades.
"They're an historical accident because women couldn't join the Navy or the Marine Corps," he said. "They joined the auxiliary, and they were given different uniforms to indicate that they weren't full sailors or Marines."
Trouble was, that cover looks a lot like the modern women's cover, and Marines decried the suggestion as a "girlie hat."
"It's not an arbitrary thing. It's not just, I woke up one morning and this is what I decided," he said. "There are reasons to do this, and whether conscious or unconscious bias, whether just viewing women differently as sailors because, if women are qualified to meet any of the standards and any of the occupations, why should we treat them differently?"
"He has been open to ask and answer questions others of a more conservative background would not," said retired Capt. Jerry Hendrix, a former naval flight officer, adding that he learned firsthand as an aviator during integration in the early 1990s that women are effective in combat.
"Mabus is sincerely interested in opening opportunities," he added. "And as a father of two daughters, I have to respect that."
