Right, firstly I'd just like to say that I'm a young 'un and have gaping holes in my military knowledge. So there is the quite real chance of me saying something stupid further down this post. Secondly, just in case I come across as one, I'm not a walt, this is a genuine request for info and advice. Basically, I will be joining the R Signals in the near future. I plan to get my first posting to 16th Airborne and become Para trained. However, looking through the handy careers book the AFCO gave me it says: I've already looked into the para bit, as that's what I plan to do. SAS bit sounds a bit silly for me, and I don't know when I'd have time to fit in writing all those books. However the Commando bit has me totally stumped. I have no idea what that would entail at all. As far as my limited knowledge can gather only the RM are commandos, i.e there is no Army Commando. How can you serve in the RM and the R Signals at the same time, bearing in mind that they are from different services. Do you have to complete RM training to serve as part of their Signals unit (not as stupid a question as it sounds, only 50% of the 16th Airborne Sigs are para trained)? If anyone could give me some info or a link to a site that would shed some light on the subject that would be very helpful. Unless I'm being a total spiv I can't find any info on it on the R Signals Army website page that lists all of the R Signals units. Thank you for your time.
