Brownlow wears two medal ribbons on his uniform. One is a police LSGC, the other appears to be the General Service Medal awarded to the armed forces, for service in Northern Ireland etc. This indicates a military background to the character.
Charles Brownlow was a Superintendent for more than seven years, he was promoted and transferred to Sun Hill in 1984, where he became the OCU Commander and coordinated the station's operations alongside his Senior Management Team of Derek Conway and Jack Meadows.
In 2000, CIB (Later the DPS) stormed into Sun Hill Police Station and suspended the entire CID team with immediate effect. Brownlow had many friends at Sun Hill however, 29 year old Borough Commander Ch. Supt. Guy Mannion despised Brownlow and had been trying his very best to put him off and remove him from Sun Hill, Mannion then used the Don Beech corruption scandal as an excuse to bully Charles into resignation. Charles was manipulated by Mannion and tendered his resignation, which forces some of the relief to believe Charles was leaving to save his own skin. It later transpires that Charles could have stayed after all and he was right all along, that Don Beech's corruption was confined to just him, and no other members of the team.
