Navy

Chris Kyle is known for being the deadliest sniper in American history. He saved countless numbers of men and women's lives while fighting across seas in Iraq.

Chris eventually retired from the Navy, and fought a battle with PTSD.

In order to fight his symptom, he continued to stay with his family and watch his two children grow. He also found time to write his book American Sniper.

He also went on and helped other war veterans who were fighting it as well, eventually leading to helping the man who shot and killed him at a firing range.
