...Army Special Forces Command said Tillman led the lead section of a platoon when the platoon's trailing team came under enemy fire.

It said that while his part of the platoon was out of danger, Tillman maneuvered his team back toward the fray in order to protect the rest of the platoon, and directed gunfire at the enemy. It said he lost his life, but his efforts helped prevent the rest of the platoon from suffering any casualties.
