The Battle of Coral and Balmoral began on 12^th May 1968 and lasted until 6^th June 1968.  The Battle was the largest and most sustained engagement of the Vietnam War involving Australian troops and was the first Australian all arms brigade sized operation since WW2.  25 Australians were KIA.  

Signals had one KIA and three WIA.  Signals deployment tactics changed because of the Battle resulting in Armoured Command Vehicles (ACV) to deploy equipment and signal personnel for signal sector defense, on all future deployments in Vietnam.

In May 2008, the 40th Anniversary Commemorations of the Battle occurred in Canberra and the highlight was a reception at The Great Hall, Parliament House hosted by the Prime Minister, The Honourable Kevin Rudd MP.   This was follow by a  memorial service the following day at the Australian Vietnam Forces National Memorial.
