Law enforcement agencies throughout the Bay Area have received more than $14 million dollars worth of decommissioned military equipment, including grenade launchers, armored vehicles, and an 85-foot speed boat armed with machine guns, records show. The acquisitions by local agencies include a $4.4 million fast patrol boat, given to the Alameda County Sheriff's office in 2005 to patrol the waterways around the Port of Oakland, a $685,000 mine resistant vehicle for the Antioch Police Department and an armored vehicle known as the MAMBA, which can withstand land mines and IEDs, for the city of Concord.
