WASHINGTON — Brig. Gen. Jeffrey Sinclair, fired from his command in Afghanistan last May and now facing a court-martial on charges of sodomy, adultery and pornography and more, is just one in a long line of commanders whose careers were ended because of possible sexual misconduct.
Sex has proved to be the downfall of presidents, members of Congress and other notables. It's also among the chief reasons that senior military officers are fired.
At least 30 percent of military commanders fired over the past eight years lost their jobs because of sexually related offenses, including harassment, adultery, and improper relationships, according to statistics compiled by the A.P.
The figures bear out growing concerns by Defense Department and military leaders over declining ethical values among U.S. forces, and they highlight the pervasiveness of a problem that came into sharp relief because of the resignation of one of the Army's most esteemed generals, David Petraeus, and the investigation of a second general, John Allen, the top U.S. commander in Afghanistan.
The statistics from all four military services show that adulterous affairs are more than a four-star foible. From sexual assault and harassment to pornography, drugs and drinking, ethical lapses are an escalating problem for the military's leaders.
With all those offenses taken together, more than 4 in every 10 commanders at the rank of lieutenant colonel or above who were fired fell as a result of behavioral stumbles since 2005.
The recent series of highly publicized cases led to a review of ethics training across the military. It also prompted Army Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, to conclude that while training is adequate, it may need to start earlier in service members' careers and be reinforced more frequently.
Still, officials struggle to explain why the problem has grown and they acknowledge that solving it is difficult and will take time.
"I think we're on the path. I think the last two defense secretaries have made this a very high priority and have very much held people accountable. But we've got a ways to go," said Michele Flournoy, a former undersecretary of defense under President Barack Obama.
She said the military must enforce a "zero tolerance" policy and work to change the culture so service members are held accountable and made to understand that their careers will be over if they commit or tolerate such offenses.
"The policy is in place," she said. "I don't know that it's as evenly and fully enforced as intended."
For top officers, the numbers are startling.
Eighteen generals and admirals, from one star to four stars, were fired in recent years, and 10 of them lost their jobs because of sex-related offenses; two others were done in by alcohol-related problems.
The figures show that 255 commanders were fired since 2005, and that 78 of them were felled by sex-related offenses. A breakdown: 32 in the Army, 25 in the Navy, 11 in the Marine Corps and 10 in the Air Force.
