Obama noted that the 28-year-old Pitts has said his honor belongs to everyone who was with him during the July 13, 2008 attack in Wanat, Afghanistan.    Obama described how Pitts defended an observation post after the eight other soldiers providing security alongside him were killed in a well-organized attack by about 200 insurgents. Obama said Pitts was bleeding, hit by shrapnel in his arms and legs and sure he would die, as he lobbed grenades and pulled himself to his knees to man a machine gun against approaching insurgents.    "That little post was on the verge of falling, giving the enemy a perch to devastate the base below," Obama said in a White House ceremony. "Against that onslaught, one American held the line."    He called in for air support that helped repel the attack and prevented the enemy from taking his fellow soldiers who had been killed.    Obama honored each of those killed in battle with Pitts by name, and asked their families to rise and be recognized, including two of their children who have grown up without a parent. He also noted it was the second wedding anniversary for Pitts and his wife, who have a 1-year-old son.    "It's going to be tough topping this one, as anniversaries go," Obama joked. But he advised Pitts, "You should try. Don't rest on your laurels after just two years."Pitts spoke after the ceremony and said he wanted people to remember the names of those who fell, not his."Standing there I thought of these incredible men. Those present here today and especially our brothers who fell," Pitts said. "Valor was everywhere that day, and the real heroes are the nine men who made the ultimate sacrifice so the rest of us could return home. It is their names, not mine, that I want people to know."
