Earlier in the posts the EMU's were mentioned and I guess that a lot of you already knew about the RAAF's 9 Squadron involvment in Vietnam but the Royal Australian Navy's 723 Squadron's role with the conflict little is known. So crank up the speakers (and the central heating) and learn a little about the 135th / RAN helicopter flight Veitnam... the EMU's.
