Seventy-five years ago, the battle of Iwo Jima was raging. In order to provide a staging area for attacks on the Japanese mainland, the Americans began the assault on the island on Feb. 19, 1945. After 36 days of fighting, the Americans secured the island at the cost of 26,000 casualties, including over 6,800 dead.

According to the U.S. Department of Veterans Affairs, less than 500,000 WWII veterans are still alive, and time is running out to honor these American heroes. Donnie Edwards is a retired NFL football player with the Kansas City Chiefs and San Diego Chargers who has spent the last 22 years giving back to the military through his Best Defense Foundation.
