The U.S. Olympic Training Center in Colorado Springs is hosting 220 servicemen and woman who are wounded, injured or ill this week for the 2^nd Annual Warrior Games.

“We have the Army, the Navy, the Marines, the Air Force, the Coast Guard and Special Operations Command all participating,” says Charlie Huebner, chief of paralympics for the U.S. Olympic Committee.

Huebner says a primary goal of the games is to encourage people with disabilities to be physically active.

Some of the athletes are the soldiers you’ve heard a lot about — injured by a roadside bomb or another combat-related injury. Others are accident victims or suffering from an illness.

Participants compete in seven sports: archery, cycling, basketball, shooting, swimming, track and field, and sitting volleyball. They are chosen proportionately from the various service branches.

In sitting volleyball the net is low so that it touches the ground. And the players don’t use wheelchairs, like in basketball, they sit on the floor and propel themselves however they can.

“Everybody’s got different injuries,” says Savage Margraf, 24, with the Marine Corps sitting volleyball team. “Some of the guys are double-amputees, some are single-amputees below the waist.

“This is actually a sport where having legs is a disadvantage because they get in the way,” Margraf says. She’s one of the few team members who still has both arms and legs.

Margraf suffers from traumatic brain injury (TBI). She says doctors attribute her TBI to two bad falls she took while serving in Iraq. One was from a watch tower on the Syrian border.

“I was helping get a 50-[caliber] barrel down — it’s a machine gun,” Margraf explains. “We had to change out the barrels because there was a sand storm. As I was coming down the stair, the second stair from the top broke and I fell.”

Now Margraf says she has trouble with her vision. She was medically retired from the military in 2008 at 21 years old. Many of those participating in the Warrior Games are young.

Teammate Jese Schag, 21, had his right leg amputated after a motorcycle accident in 2009. He played sitting volleyball in the first Warrior Games last year.

“It’s all about speed and you got to have good hands,” Schag says. “You got to be able to react — put your hands on the floor and then bring them up to get the ball.”

Margraf says the competition is fun, but she’s really here for inspiration.

“We have a swimmer who is a double-amputee and blind,” Margraf says. “How can you not come to this and leave with some sort of motivation and know that there are people that are way worse than you and they are trying?”

The Defense Department and the U.S. Olympic Committee organize the Warrior Games. Opening ceremonies were on May 16. The sitting volleyball finals will wrap up the competition on May 21. Copyright 2011 National Public Radio. To see more, visit http://www.npr.org/.
