Quick Bio from Wikipedia:
Doakes enlisted in the U.S. Army and went on to become an Army Ranger, serving with the elite Regimental Reconnaissance Detachment. After spending many years in black operations, Doakes gave up his military career, electing instead to use his skills to help innocent civilians. Doakes’s police career grinds to a halt when he receives excessive force citations and proves he cannot work well with others (unless leading them). Doakes had a relationship with LaGuerta, whom he made a point of listening to, and was partners with her, but their partnership ended when LaGuerta arrested a high-profile drug dealer in a drug bust and got promoted.
