Subic Bay A CO

**Subic Bay A Company** (often referred to as "A CO") was a pivotal U.S. military unit stationed at Subic Bay Naval Base in the Philippines during the Cold War era. Tasked with base security, logistics support, and rapid reaction to regional contingencies, A CO played a crucial role in maintaining the operational readiness of one of America's largest overseas naval installations. The unit routinely participated in joint exercises with the Philippine military and other allied forces, strengthening regional partnerships and enhancing interoperability. Following the closure of Subic Bay Naval Base in 1992, A CO was deactivated, marking the end of an important chapter in U.S.-Philippine military cooperation.
