United States Army 377th Support Command Insignia Patch, SSI Patch

The 12th Port of Embarkation, later designated 377th Theater Sustainment Command, was constituted on 2 July 1942 and was activated 5 July 1942 at Fort Dix, New Jersey. The unit was converted, reorganized, and redesignated 7 November 1942 as the 12th Port. The unit was inactivated 4 January 1946 at Camp Kilmer, New Jersey and later redesignated 3 November 1948 in New Orleans, Louisiana, as the 377th Transportation Major Port. On 11 September 1950 the 377th was called to Camp Kilmer, New Jersey. Later, the unit moved to Fort Eustis, Virginia and stayed on active Federal Service until 10 October 1952. From 1953 until 1963, the 377th remained in a Reserve status and experienced several changes in unit designation.

On 31 December 1965, the unit was re-designated as the 377th Support Brigade under the Army Logistical Concept. On 16 October 1979, it was renamed the 377th Corps Support Command. It retained the designation until 16 July 1981 when it was designated as a Theater Army Area Command (TAACOM). On 1 October 1998 the TAACOM wartime mission expanded and the unit designation was changed to the 377th Theater Support Command.

The TSC serves as a Force Support Package unit with an ongoing support mission in its area of operation. Over 500 downtrace units throughout the United States, Puerto Rico, Guam and the Virgin Islands provide support to the TSC for training and wartime mission guidance. Whether at home station, deployed across the country or overseas, the TSC trains to achieve its peacetime and wartime mission of providing command and control of assigned units to ensure and maintain a high state of readiness. The TSC prepares wartime-aligned units to accomplish their mission by developing, executing and evaluating training. The TSC provides daily logistics support to its wartime higher headquarters for missions and exercises.

This SSI patch comes from a lot manufactured in 1970 as official USGI military patch with a merrowed edge.
