The Active Duty Center provides a core space to include self-directed and directed recreational activity components to meet the needs of both Active-Duty personnel and the Single Marine population. We emphasize an alcohol-free and tobacco-free environment per the MCO 1700.39 (chapter 26). We strive to maintain a space that Marines can feel at home while simultaneously keeping the high traditions and standards that the Marines Corps expects from everyone that comes aboard MCRD San Diego.
