While few Americans are sheltered from the jolt of the recent economic crisis, the nation’s newest veterans, particularly the wounded, are being hit especially hard. The triple-whammy of injury, unemployment and waiting for disability claims to be processed has forced many veterans into foreclosure, or sent them teetering on its edge, according to veterans’ organizations.

The problem is hard to quantify because there are no foreclosure statistics singling out veterans and service members. Congress recently asked the Veterans Affairs Department to find out how badly veterans were being affected, particularly by foreclosures. The Army, too, began tracking requests for help on foreclosure issues for the first time. Service organizations report that requests for help from military personnel and new veterans, especially those who were wounded, mentally or physically, and are struggling to keep their houses and pay their bills, has jumped sharply.

“The demand curve has gone almost straight up this year,” said Bill Nelson, executive director for USA Cares, a nonprofit group that provides financial help to members of the military and to veterans. Housing, Mr. Nelson said, “is the biggest driver in the last 12 months.”

Congress has recently taken small steps to help, banning lenders from foreclosing on military personnel for nine months after their return from overseas, up from three months, and ensuring that interest rates on their loans remain stable for a year. Another relief bill to prevent certain injured veterans from losing their homes while they wait for their disability money was signed into law in October. The protection is good for one year.

“We owe these men and women more than a pat on the back,” said Senator John Kerry, Democrat of Massachusetts, who introduced one of the bills.
