Both Mark (left) and Luke (right) Radlinski were lieutenants in the Navy. Luke deployed in 2001 to the Persian Gulf in support of the conflict in Afghanistan, and his brother, Mark, went to Iraq in 2006. But just before Mark left, they had a fight and parted on bad terms.

At StoryCorps they talk about Luke’s email to Mark that helped them move on, and their feelings upon Mark returning home.
