The suicide rate among the nation’s active-duty military personnel has spiked this year, eclipsing the number of troops dying in battle and on pace to set a record annual high since the start of the wars in Iraq and Afghanistan more than a decade ago, the Pentagon said Friday.

Suicides have increased even as the United States military has withdrawn from Iraq and stepped up efforts to provide mental health, drug and alcohol, and financial counseling services.

The military said Friday that there had been 154 suicides among active-duty troops through Thursday, a rate of nearly one each day this year. The figures were first reported this week by The Associated Press.

That number represents an 18 percent increase over the 130 active-duty military suicides for the same period in 2011. There were 123 suicides from January to early June in 2010, and 133 during that period in 2009, the Pentagon said.
