I go back to my original argument that it's all recruiting-focused. The navy, as well as every other branch, has to have more metal, different uniforms, etc....anything to separate it from the other branches in hopes of "looking cooler" than the others. I knew a former USMC drill instructor who told me that when he polled his basic training class, about 1/3 of them chose the marines because of the uniform...maybe the navy is hoping the same thing here.
In this case it is not, it is mainly being driven by a single person who wants to leave a mark and make some intel types feel better about themselves.
