The Governor-General, Sir Peter Cosgrove AK MC, has formally approved the awarding of the citation in recognition of the military assistance provided to the former Republic of Vietnam (South Vietnam) while under the operational command of the United States Military Assistance Command (MACV).
Minister Chester said 547 Signal Troop was raised in 1966 and deployed to Vietnam as Australia’s contribution to the US intelligence network.
"The troop’s primary role was to locate and monitor enemy radio signals in order to identify their strength, location, capability and future intentions," he said.
The troop was under operational control of the US Army Security Agency’s 509th Radio Research Group and was assigned to the 303rd Radio Research Battalion. The troop’s deployment to Vietnam included responsibility for direct support to the Australian Task Force and American units operating under the US II Field Force Vietnam command.
"Throughout their deployment to Vietnam, the troop was credited with providing early warning of imminent large scale enemy action against Australian, US and Thai forces, and were directly credited with saving hundreds of lives," Minister Chester said.
Minister Chester encouraged veterans and family members of deceased veterans of 547 Signal Troop to apply through the Directorate of Honours and Awards at the Department of Defence for the citation.
To be eligible for the citation insignia, members must have served in Vietnam under the command of MACV and posted to 547 Signal Troop during the eligible dates, 13 June 1966 to 23 December 1971.
Minister Chester said, "Due to the extreme secrecy surrounding the troop’s operations, their presence in Vietnam continued to be a closely guarded secret. Even today the troop does not appear on many maps drawn up by the Australian Task Force or on a model at the Australian War Memorial showing the locations of all Australian units at Nui Dat."
