The Orangetown Police Auxiliary is an active group of volunteers who work closely with the regular officers and are invaluable during special events, parades and other details where additional traffic and crowd control becomes necessary. The auxiliaries have their own internal rank structure and chain of command. However, they are under the command of the regular police ranking officer on duty.
The Auxiliary uniform patch evolved from the Triangular dark blue patch which did not have the New York State Seal, but the "CD" for Civilian Defense. The "CD" patch was replaced in the sixties with the standard triangular dark blue patch which incorporated a band over the top arc which read "AUXILIARY". That patch was eventually replaced with the new Orangetown patch which also incorporated a band over the top arc that reads "AUXILIARY". Some earlier versions had a band that read "AUXILIARY POLICE". The most recent edition, with a light blue background, includes all the information on one patch.
