Shore Patrol. The center was swiftly put out of business in September 1972 when martial law was declared in the Philippines (see below). SOS offices There were SOS offices in Oakland, serving the San Francisco Bay Area, and Los Angeles. In Los Angeles, the office opened in January 1972 with SOS standing for Support Our Soldiers, carrying on efforts initiated several years earlier by supporters of the GI Coffeehouse movement. They began putting out a newsletter called SOS News and announced in their first issue that they were “a support office for the GI Movement.” They pledged to take responsibility for “raising money, providing literature and films, recruiting staff, maintaining communications and providing publicity for GI coffeehouses and projects.” In Oakland, the Support Our Soldiers office offered similar support to the GI movement.
