If you had to guess, out of all the branches of the United States military, which ones are the most professional? The least?

It’s a spicy question, but one that was actually addressed by a recent “force-wide look at misconduct among senior military officers” by Defense Secretary Ash Carter’s senior advisor for military professionalism, Rear Admiral Margaret “Peg” Klein.

The findings are immensely interesting.

“The Army and the Marine Corps have a very mature profession of arms,” said Klein.

“The ground forces, they send really junior people into leadership positions. They have company command, they have O-3s going into command, and their professional identity is learned very early on,” Klein said, referring to the paygrade for captains in the Army, Marines and Air Force. Navy O-3s are lieutenants. Yet the Navy and the Air Force, historically, “are very technically focused,” she said.

Her office was created back in 2014 by then-Pentagon chief Chuck Hagel in the wake of various scandals and poor behavior from top officers.

This from the Military Times:

Klein’s office, initially created as a two-year project, is slated to stand down in March. She has asked Defense Secretary Ash Carter to extend its life through January 2017. “A little bit more time is a really inexpensive investment in getting traction in these ideas that we’re trying to institutionalize,” she said.

The slew of scandals that emerged a few years ago made for stunning headlines. A Navy corruption scandal. An Air Force major general who oversaw nuclear missiles was fired after his drunken bender on a visit to Moscow offended both his Russian hosts and his own staff. An Army four-star general was reprimanded for spending lavishly on official trips.

But Klein said those are anecdotal and she’s found no systemic or deeply rooted cultural problem. “We’re seeing numbers within historic norms,” she said. “We always want to be shooting for a target that decreases the incident rate.”

“We think the right answer is a little different for each service based on their heritage.”
