Vietnam WarEdit

The 1st Signal Brigade was activated on 1 April 1966 in South Vietnam.[2] The brigade's mission was to originate, install, operate, and maintain a complex communication system that fused tactical and strategic communications in Southeast Asia under a single, unified command. The formation of the brigade brought together three signal groups that were already in South Vietnam.

At the peak of the Vietnam War the brigade consisted of more than 23,000 soldiers, in six Signal groups (including the 160th Signal Group), 22 signal battalions and several communications agencies, making the 1st Signal Brigade the largest signal unit in the U.S. Army at the time.[3][4]

South Korea to presentEdit

On 7 November 1972 the brigade was relocated to the Republic of Korea under the United States Army Strategic Communications Command.[5] On 29 January 1973 the 1st Signal Brigade was reestablished by General Order 56 from HQ, USASTRATCOM. The brigade's mission in South Korea is to provide communications support to the Eighth United States Army, United States Forces Korea and the United Nations Command. The brigade was also given the mission of installing, maintaining and operating the Defense Communications System in South Korea.[3]
