Cheers for this, I have done some research along these lines and found it very useful. I have a couple more questions on the same theme. Firstly, does the slightly removed nature of postings to some of the more distant radar stations mean there is less opportunity among this specialisation for travel, adventure training, and most importantly sport? Finally, as I had asthma as a child I am not eligible for aircrew. Does this mean I cannot serve as a Fighter Controller on board a Sentry E 3D?
