Coast Guard Pacific Area is set to commission a new port security unit (PSU 312). Vice Adm. Harvey Johnson, commander of Coast Guard Pacific Area, will be the presiding official for the ceremony in which Cdr. Donald G. Huenefeld will assume responsibility for PSU 312. PSUs provide a force of six active duty and 140 reserve members who possess specialized skills, capabilities and expertise to perform a broad range of port security and harbor defense missions. They are the model on which Coast Guard law enforcement detachments and maritime safety and security teams are based. PSUs are capable of augmenting Coast Guard or Department of Defense forces during major marine events or law enforcement operations focused primarily in ports, harbors, internal waterways and coastal regions.
