Marietta-Cobb-Smyrna
Major John Koehler, Assistant Division Commander
A twenty-two year veteran of the Cobb County Sheriff’s Office,
Major Koehler has served in multiple assignments within the agency during his
career. Prior to assuming his current position, he was an undercover investigator
in the Narcotics Unit as well as serving in various capacities in the Detention Division,
Internal Affairs Unit, Court Security and in the Civil and Warrant Sections. During his
career, he has received advanced training and specialized in the areas of narcotics
investigations and undercover operations. This training and experience prepared him for
his role as Unit Commander of the MCS Narcotics Unit, a position he has held since 1995.
The Marietta/Cobb/Smyrna (MCS) Narcotics & Intelligence Unit is a multi-jurisdictional task force formed
in 1980 and commanded by a Major from the Cobb County Sheriff’s Office, with a primary mission of drug interdiction
within Cobb County. Initially, the unit was comprised of personnel from the Cobb County Sheriff’s Office, Marietta
Police Department, Cobb County Police Department, Smyrna Police Department and the Cobb County District Attorney’s
Office to bring the necessary manpower and resources together in a cooperative effort to bring drug dealers before the
criminal justice system.
In 2001, the Unit added personnel from the Acworth Police Department, Kennesaw Police Department and the Georgia National Guard.
The agencies work together in a cumulative effort to stem the flow of illegal substances, organized crime and vice crimes within our community.
