The word "hero" is tossed around so casually these days that it has almost lost its meaning. Then comes the story of Army Sgt. Paul Smith, who reminds us what a real hero is. The 33-year-old soldier from Tampa was killed April 4 after valiantly fending off an Iraqi assault on his command post.

Smith's bravery in saving his troops is a story worth repeating. He was leading two dozen engineers building a prison at Baghdad International Airport when the contingent was attacked by 100 elite Republican Guards. As his soldiers fell around him, outmanned and outgunned, Smith dodged snipers and rocket grenades to tend to the wounded. He ran to a Humvee, grabbed a grenade and blew back the charging Iraqis. Then Smith climbed atop his armored vehicle and manned the .50-caliber machine gun, emptying four boxes of ammo over 90-minutes.

Witnesses said he killed 30 to 50 Iraqis and stopped the enemy from overrunning his post. When the firing stopped and the Americans regrouped, his men found Smith shot in the head. He was the only American to die in the fight.
