Well, I'm glad at least some people get to go where they want.
I however, have had 4 bases in 2 and a half years! None of which I wanted to go to, and on one occasion, after having finally set up some form of normal life at my 'permanent' base' I was informed that I was no longer required there and that in one months time my base will be XYZ.
I don't want anybody thinking It's all happy and nice and permanent if you get the base you want. As being on BRK means that in 30 days time you could be based in the arse end of nowhere and there is nothing you can do about it!
