6th Communication Battalion

6th Communication Battalion was activated on 15 May 1957 at Fort Schuyler, Bronx, New York, as the 1st Communication Support Battalion and were re-designated on 1 July 1962 as the 6th Communication Battalion. The battalion was called to active duty in March 1970 for service in the U.S. postal strike of 1970.

The battalion participated in support of Operation Desert Storm in Southwest Asia from December 1990 to April 1991. They relocated during July 1997 to Floyd Bennett Field, Brooklyn, New York. Following the attacks of September 11, 2001, many 6th Comm Marines volunteered for Operation Rainbow Hope, organized by the New York State Naval Militia. This operation, which also included members of other local reserve units, provided security for New York City Metropolitan Area bridges, tunnels, the mayoral residence, relief supply distribution points, ground zero, and other potential target areas. During the operation, a number of Rainbow Hope volunteers were billeted on Governor's Island. The entire battalion was mobilized in 2003 in support of Operation Enduring Freedom. They participated in Operation Iraqi Freedom from March to June 2003. After returning to New York, the unit was demobilized in September 2003. Elements of the battalion have again mobilized and deployed in support of Operations Iraqi Freedom and Enduring Freedom since June 2004 to the present.

Two Marines from the unit were killed during the September 11 attacks on the World Trade Center in New York City. The Marines were Gunnery Sergeant Mathew Garvey, a firefighter with New York City Fire Department Squad Company 1 and Sergeant Major Michael Curtin, a police officer with New York City Police Department Emergency Service Unit Truck 2.
