Meet Sgt. "raghead": "He has recruited 10 men to the program in little more than a year, a record unrivaled in the Army National Guard. Still, he is an unlikely foot soldier in the campaign. His own evolution — from a teenage immigrant who landed in North Dakota after the first gulf war to a spit-and-polish sergeant — has been marked with private suffering. In boot camp, he was called a “raghead.” Comrades have questioned his patriotism. Last year a staff sergeant greeted him by calling out, “Here comes the Taliban!” He remembers a day in 2002 when the comedian Drew Carey visited a base in Saudi Arabia where he was working. During a skit, Sergeant Murad recalled, Mr. Carey dropped to the ground to mimic the Muslim prayer. As the troops roared with laughter, Sergeant Murad walked out. “I thought about my mom when she prays, how humble she is,” he said.
