He was commissioned into the Green Howards in 1971, and his first tour of duty was in Belfast as a platoon commander. During his second tour of duty, also in Northern Ireland, Dannatt was awarded the Military Cross. Following a major stroke in 1977, Dannatt considered leaving the Army, but was encouraged by his commanding officer to stay. After staff college, he became a company commander and eventually took command of the Green Howards in 1989. He attended and then commanded the Higher Command and Staff Course, after which he was promoted to brigadier. Dannatt was given command of 4th Armoured Brigade in 1994 and commanded the British component of the Implementation Force (IFOR) the following year.
