Reserve deputies come from all walks of life with the desire to serve the 1.2 million residents of Allegheny County including Pittsburgh, PA. Citizens who want to support your country, state, and county can make a difference by joining the unit.

Uniformed Street Division

The Street Unit is staffed by 80+ uniform deputies. Members typically work 100+ hours a year. By far the most extensive activities of the Reserve in terms of man-hours are the crowd-control services provided to local communities and to charitable organizations.  This assistance at carnivals, festivals, parades and other special events not only assures an added measure of public safety, but also in many cases frees the use of local police officers for normal duties. 

 Many small communities would not be able to handle such events without this assistance, and could certainly not afford the cost in man-hours of the services which the Sheriff's Reserve provides free of charge.

Motorcycle Division

In addition to being qualified in the Uniform Division the Motorcycle Unit that provides motorcycle escort duty for events, perform traffic control, and parade duty for the Sheriff. Motorcycles marked units owned and maintained by each motor-officer again at no expense to the public.  

Training Division

The Firearms Unit is the professional training unit of the organization. Instructors are professionally trained and give modern law enforcement training to new recruits, mandatory updates, and annual firearm qualifications to existing deputies.  Training consists of a rigid police training curriculum administered by certified professionals. Deputy’s train in handcuffing, edge weapon defense with dis-arm and retention techniques, PPCT Pressure Point Control Techniques, OC (oleoresin capsicum spray), use of the asp/baton, arresting techniques and firearms. Firearms training is an intensive and mandatory requirement. It consists of 70 hours of Certified Instructor Qualified level leadership.
