The Imperial County Sheriff’s Office Aerosquadron flies missions in support of the Sheriff’s Office search and rescue units and the off road and boating units.



The De Anza Rescue Unit is a group of volunteers who use their off road knowledge and tracking skills to locate and rescue lost or injured persons in the Imperial County. All De Anza members provide their own equipment and supplies. The DeAnza Mobile Command Post carries a wide variety of rescue equipment and also allows them to coordinate with law enforcement and oversee all operations while in the field.


The Sheriff’s Posse is the oldest volunteer group, dating back to the 40’s or early 50’s. The men and women of the posse use their horses to support the Sheriff’s Office in many ways. From security to search and rescue, and the best BBQ you’ll ever want to taste, the Posse does it all!


The Sheriff’s Reserves are the only sworn law enforcement volunteers. After receiving their California Peace Officers Standards and Training (POST) certificates, Reserves do security details, work patrol, the courts, OHVEST, BEST and wherever they are needed.
