The deployment and redeployment of US forces in support of combatant commander (CCDR) requirements are a series of operational events enabled by logistics. These activities are planned and executed by both the supported and supporting commanders. To effectively support multiple requirements, and apply the right level of priority and resources to each, requires effective global force management (GFM). GFM aligns force assignment, apportionment, and allocation methodologies in support of the National Defense Strategy, joint force availability requirements, and joint force assessments. Force projection is the ability to project the military instrument of national power in response to military operations. Force projection allows a joint force commander (JFC) to position and concentrate forces to set the conditions for mission success. The joint deployment and redeployment processes consist of four phases: planning, predeployment/pre-redeployment activities, movement, and joint reception, staging, onward movement, and integration (JRSOI).
