What is Mobilization? When you receive your mobilization orders, mobilization is simply reporting to your Army Reserve Home Station, which is usually your Army Reserve Center. Here, your unit will begin preparing you for Activation.


Presidential Reserve Call-up (PRC)
The President has the authority to involuntarily augment the active forces by a call-up of up to 200,000 members of the selected reserve for a period up to 270 days to meet mission requirements within the continental United States (CONUS) or overseas. The President must notify Congress within 24 hours and state the reason for his action.

Partial Mobilization
The President has the authority to mobilize no more than 1,000,000 reservists (units and individuals from all services), for 24 months or less, and the resources needed for their support to meet the requirements of war or other national emergency involving an external threat to national security.

Full Mobilization
Congress must declare that a state of national emergency exists to call up all forces, including Army Reserve and Army National Guard units, Individual Ready Reserve, Standby Reserve and members of the Retired Reserve, and the resources required for their support. The duration is the length of the emergency plus six months.

Total Mobilization
Once a state of national emergency exists, Congress can extend full mobilization by activating and organizing additional units beyond the currently approved force structure. Total mobilization brings the industrial base up to full capacity to provide the additional resources, equipment and production facilities needed to support the armed forces of the nation, as done in World War II.
