The 501st Military Intelligence Brigade, headquartered at Camp Humphreys, focuses on supporting warfighters by providing indications and early warning of actions by opposing forces who could threaten a tense, but stable, peace on the Korean Peninsula.

In the event of hostilities, the brigade's mission shifts to providing combined, multi-discipline intelligence and force protection support to the United Nations Command/Combined Forces Command, the CFC Ground Component Command and their subordinate units (primarily the 8th U.S. Army and the forces of the Republic of Korea).
