Washington ? The toll for a nation long at war is evident in military homes: The divorce rate in the armed forces edged up again in the past year despite many programs to help struggling couples, and the rate now is a full percentage point higher than around the time of the attacks of Sept. 11, 2001.

There were an estimated 27,312 divorces among roughly 765,000 married members of the active-duty Army, Air Force, Navy and Marine Corps in the budget year that ended Sept. 30, the Pentagon said Friday.

That’s a divorce rate of about 3.6 percent for fiscal year 2009, compared with 3.4 percent a year earlier, according to figures from the Defense Manpower Data Center. Marriages among reservists failed at a rate of 2.8 percent compared with 2.7 the previous year.
