The range of military operations encompasses operations in peacetime, conflict, and war. Area Support Groups support operations across the range of military operations. Though ASG elements function in a peacetime environment, they must be ready to quickly transition from peace to operations other than war and war.
ASG units may provide support to combat-ready forces in their crisis support or power projection role. Selected ASG elements may augment the Corps Support Command (COSCOM) or Division Support Command (DISCOM) when support requirements exceed their support capabilities. They may deploy from a forward presence site in response to a crisis or remain at that forward site to receive and process follow-on forces. (note: this is the mission that the 111th ASG performed when mobilized for Operation Joint Guard, the Bosnian peacekeeping mission, in 1997).
ASGs may tailor a slice of support to set up a forward support base or provide support at an intermediate staging area. ASG units may also locate ina friendly nation outside the supported Commander-in-Chief's (CINC's) region or operate a support base from amphibious shipping or mobile sea bases.
An Area Support Group consists of:
The number and type of units that fall under the ASG's command will vary, depending on whether the unit is supporting a mission other than war or a wartime mission.
