The DIMA Program

Current manning of the active Army is capable of meeting peacetime needs; however, in the event of mobilization, trained augmentees capable of immediately filling required positions are essential. The Drilling Individual Mobilization Augmentee (DIMA) Program provides this augmentation.

Members of the DIMA Program are a vital and immediate link in the overall military strength of our nation. Their role is that of first-line augmentation in the event our nation's forces are called up or mobilized due to war, military operations other than war, or a national emergency. By maintaining a high state of readiness, they provide the support needed to meet our increased mission requirements.
