David Fisher played football and basketball in high school, and those who knew him remember him as always upbeat, with a smile on his face.
"He was so funny. He always had something to say," said friend Lindsay Edwards. "He was good at anything he put his mind to."
Fisher, 21, of Watervliet, N.Y., died Dec. 1 when the Humvee in which he was riding overturned. His National Guard unit was stationed at Newburgh, N.Y.
Fisher enlisted in the National Guard in November 2001 after graduating from high school. His captain, Mark Walsh, said he remembered Fisher's grin.
"He was smiling so much I thought he was up to no good," Walsh said. "Apparently, it was just the opposite."
Fisher is survived by his father, John Fisher, and mother, Victoria DiMura.
