The 135th Assault Helicopter Company was organized at
Fort Hood, Texas on 1 February 1967.
In October 1967 the unit deployed to Vung Tau,
Republic of Vietnam. At the time of deployment,
the Australian Government dispatched a Navy Helicopter flight
to Vietnam consisting of eleven officers and thirty-six enlisted
men. The Australian flight was assigned to the 135th, and the
unit became known as an "Experimental Military Unit",
or EMU for short.
The unit's first roll in Vietnam was to support the
Royal Australian Task Force and other free-world units
working in III and IV Corps. To facilitate operations,
the 135th moved to Blackhorse in December 1967
and then to Bear Cat in November 1968.
Working as part of the 214th CAB and 222nd CAB,
the EMU's wrought devastation on the Viet Cong from the
southern edges of the U Minh Forest to the
Bamboo of Bu Dop and east to the boundaries of II Corps.
On 8 September 1970, the EMU's moved again,
this time to Dong Tam, supporting strictly
Vietnamese Army units in the Delta.
As other Aviation units in the Delta deactivated, the only
US/Australian helicopter unit in existence took up the slack.
The 135th daily flew great distances from home station in
support of the war effort. As the only completely integrated
Multi-national Helicopter Company fighting in Viet Nam,
the EMU's developed pride and dedication to their motto,
"GET THE BLOODY JOB DONE".
The gunship platoon (TAIPANS) adopted their own motto,
In 1971, The EMU's moved to Di An.
In June 1971, the Royal Australian Navy portion of the
135th deactivated and was replaced by US personnel.
The 135th continued to carry out their mission
as well as the traditions of the EMU's.
The EMU's flew their final mission, a combat assault in support of the
25th ARVN Division in Tay Ninh, on 20 January 1972.
Stand-down operations began the following day.
