Hi, jst wondered if anyone in the know could shed some light on 4/73 for me? I'm currently serving as a Helo tech with commando helicopter force, Royal Navy, but i'm looking for a change in career path. Whilst i was serving out in Basrah i saw the posters for 4/73 Battery and just wanted to know what they did exactly. Also, i wanted to know how tough the course is? I'm pretty fit, (hopefully will have completed All arms commando course by xmas) but wanted to know what the main points of failure were? Does anyone on here serve with them now? If so, are there many non-army members of 4/73 battery? (Especially Navy). Cheers in advance.
