"We're asking a lot of soldiers these days," said Roy Wallace, director of plans and resources for Army personnel. "They're humans. They have all sorts of issues back home and other places like that. So, I'm sure it has to do with the stress of being a soldier."
The increase comes as the army continues to bear the brunt of the war demands with many soldiers serving repeated, lengthy tours in Iraq and Afghanistan, notes news agency AP.
Military leaders — including Army Chief of Staff Gen. George Casey — have acknowledged that the army has been stretched nearly to the breaking point by the combat.
The army defines a deserter as someone who has been absent without leave for longer than 30 days. The soldier is then discharged as a deserter.
About nine in every 1,000 soldiers deserted in fiscal year 2007, which ended Sept. 30, compared to nearly seven per 1,000 a year earlier. Overall, 4,698 soldiers deserted this year, compared to 3,301 last year.
While the Army does not have an up-to-date profile of deserters, more than 75 percent of them are soldiers in their first term of enlistment. And most are male.
Soldiers can sign on initially for two to six years. Wallace said he did not know whether deserters were more likely to be those who enlisted for a short or long tour.
At the same time, he said that even as desertions have increased, the army has seen some overall success in keeping first-term soldiers in the service.
There are four main ways that soldiers can leave the Army before their first enlistment contract is up:
_They are determined unable to meet physical fitness requirements.
_They are found to be unable to adapt to the military.
_They say they are gay and are required to leave under the so-called "don't ask, don't tell" policy.
_They go AWOL (absent without leave).
According to Wallace, in the summer of 2005, more than 18 percent of the soldiers in their first six months of service left under one of those four provisions. In June 2007, that number had dropped to about 7 percent.
The decline, he said, is largely due to a drop in the number of soldiers who leave due to physical fitness or health reasons.
Army desertion rates have fluctuated since the Vietnam War — when they peaked at 5 percent. In the 1970s they hovered between 1 and 3 percent, which is up to three out of every 100 soldiers. Those rates plunged in the 1980s and early 1990s to between 2 and 3 out of every 1,000 soldiers.
Desertions began to creep up in the late 1990s into the turn of the century, when the U.S. conducted an air war in Kosovo and later sent peacekeeping troops there.
The numbers declined in 2003 and 2004, in the early years of the Iraq war, but then began to increase steadily.
In contrast, the Navy has seen a steady decline in deserters since 2001, going from 3,665 that year to 1,129 in 2007.
The Marine Corps, meanwhile, has seen the number of deserters stay fairly stable over that timeframe — with about 1,000 deserters a year. During 2003 and 2004 — the first two years of the Iraq war — the number of deserters fell to 877 and 744, respectively.
The Air Force can tout the fewest number of deserters — with no more than 56 bolting in each of the past five years. The low was in fiscal 2007, with just 16 deserters.
