Army officials said 1st Lt. Joseph Guerra, who at the time was a 2nd Lt., pushed a fellow soldier to the ground and covered her with his own body to protect her from incoming gunfire.
Once the shooter ran away, officials said Guerra and his fellow soldier quickly rendered first aid to three victims who were injured during the attack. He then remained with the victims until paramedics arrived.
Guerra's actions ultimately saved the lives of four people.
"If I was trained to do it why not do it," 1st Lt. Guerra said. "They would do the same thing."
