officers wore the same dark green uniforms that Sheriff's Deputies wore until the late 40s, but with unique "Los Angeles County Guard" patches and a bear-top shield badge instead of a star. From the 1950s to the adoption of the department-wide tan-and-green uniform, security officers wore differing uniforms with patches depending on the county department they worked for. Department of Health Services officers wore all-tan uniforms, Mechanical Department officers were issued tan shirts and brown pants, and Park Patrol officers had tan-and-green uniforms, similar to the Sheriff's Department. The badge was the standard Los Angeles County design, being a shield, surmounted by a bear, of gold-colored metal with silver-colored ribbons. The seal of the county of Los Angeles was superimposed on the center of the badge, with the words "County of Los Angeles" on a ribbon just under the bear. A ribbon indicating the name of the agency "Office of Public Safety" appeared just above the seal of the county. The title of the position of the person authorized to wear the official badge was inscribed on a ribbon placed just below the seal of the county and the serial number of the badge appeared at the bottom of the badge below the title of the position. Badges of predecessor Safety Police and departmental security agencies were of the same design, but of all gold-colored metal without silver ribbons, and with the specific department name and position listed. Officers were issued the Glock 22 .40cal pistol, although some officers in special units carried the smaller Glock 23, or the larger Glock 21. 45ACP pistol. They retired their aging stock of Beretta 92F and 92FS's in 2006 which were initially issued in 1988. Officers were authorized to carry firearms off duty and were issued a flat-badge for identifying themselves as peace officers when not in uniform. While on patrol, officers had rapid access in most vehicles to an array of weapons including tasers, AR-15's, Mossberg 590 shotguns, less-lethal (bean bag) shotguns, and 40mm launchers. Most patrol assignments drove Ford Crown Victoria Police Interceptor police cars equipped with, as with the majority of police vehicles, touch screen computers, emergency lights & sirens, back-seat partitions, and push bumpers. The department changed their vehicle graphics in 2007 to increase their recognition with the public. GMC Yukons, Chevrolet Tahoes, and ATV's were common within the department as well.
