As wars lengthen, toll on military families mounts

"There's nothing that has prepared many of our families for the length of these deployments," said Rene Robichaux, social work programs manager for the U.S. Army Medical Command. "It's hard to communicate to a family member how stressful the environment is, not just the risk of injury or death, but the austere circumstances, the climate, the living conditions."

An array of studies by the Army and outside researchers say that marital strains, risk of child maltreatment and other problems harmful to families worsen as soldiers serve multiple combat tours.

For example, a Pentagon-funded study last year concluded that children in some Army families were markedly more vulnerable to abuse and neglect by their mothers when their fathers were deployed in Iraq and Afghanistan.

In Iraq, the latest survey by Army mental health experts showed that more than 15 percent of married soldiers deployed there were planning a divorce, with the rates for soldiers at the late stages of deployment triple those of recent arrivals.

For the Army, especially, the challenges are staggering as it furnishes the bulk of combat forces. As of last year, more than 55 percent of its soldiers were married, a far higher rate than during the Vietnam war. The nearly 513,000 soldiers on active duty collectively had more than 493,000 children.

Jessica Leonard at Fort Campbell says family support programs there have improved since her husband's first combat tour, helping her feel more self-reliant. Yet she's convinced that domestic violence and divorce are rising at the base, which is home to the 101st Airborne Division.

"Infidelity is huge on both sides--a wife is lonely, she looks for attention and finds it easier to cheat," she said. "It does make even the most sound marriages second-guess."

Among soldiers coming home, whether for two-week breaks that often end with wrenching good-byes or for longer stays, she sees evidence of lower morale and rising depression.

"They come home, and find that problems are still there," she said. "Instead of a refreshing R-and-R, a nice little second honeymoon, it's battle for two weeks."

There have been some horrific incidents shattering families of soldiers back from the wars--a former Army paratrooper from Michigan charged with raping and beating his infant daughter; a sergeant from Hawaii's Army National Guard accused of killing his 14-year-old son as the boy tried to save his pregnant mother from a knife attack by the soldier.
