WASHINGTON — Uncle Sam may not want you after all.

In sharp contrast to the peak years of the Iraq and Afghanistan wars, the Army last year took in no recruits with misconduct convictions or drug or alcohol issues, according to internal documents obtained by The Associated Press. And soldiers already serving on active duty now must meet tougher standards to stay on for further tours in uniform.

The Army is also spending hundreds of thousands of dollars less in bonuses to attract recruits or entice soldiers to remain.

It’s all part of an effort to slash the size of the active-duty Army from about 570,000 at the height of the Iraq war to 490,000 by 2017. The cutbacks began last year, and as of the end of March, the Army was down to fewer than 558,000 troops.

For a time during the wars in Iraq and Afghanistan, the Army lowered its recruiting standards, raising the number of recruits who entered the Army with moral, medical and criminal waivers.

Recruits with misdemeanors, which could range from petty theft and writing bad checks to assault, were allowed into the Army, as well as those with some medical problems or low aptitude scores that might otherwise have disqualified them.

A very small fraction of recruits had waivers for felonies, which included convictions for manslaughter, vehicular homicide, robbery and a handful of sex crimes. The sex crimes often involved consensual sex when one of the individuals was under 18.

In 2006, about 20 percent of new Army recruits came in under some type of waiver, and by the next year it had grown to nearly three in 10. After the Defense Department issued new guidelines, the percentage needing waivers started to come down in 2009.

Now, as the Army moves to reduce its force, some soldiers will have to leave.

Officials say they hope to make cuts largely through voluntary attrition. But Gen. Ray Odierno, the Army chief of staff, has warned that as much as 35 percent of the cuts will be “involuntary” ones that force soldiers to abandon what they had hoped would be long military careers.

“This is going to be hard,” said Gen. David Rodriguez, head of U.S. Army Forces Command. “This is tough business. As we increase things like re-enlistment standards, some of the people who were able to re-enlist three years ago won’t be able to re-enlist again.”

Waivers have long been a source of debate. Military officials have defended the process, saying it allows good people who once made a minor mistake to enlist. But mid-level officers serving in Iraq and Afghanistan also told top defense officials that the dramatic rise in the number of bad-behavior waivers was a problem, that they were often spending too much time on “problem children.”

Steven Dale Green, a former 101st Airborne Division soldier, came into the Army on a morals waiver because of an earlier problem with drugs. He is now serving five life terms for killing an Iraqi family and raping and killing the 14-year-old daughter in March 2006.
