Trouble is RAF controllers don't give you a position check in the same manner that civil ones do eg civil controllers are required to give you a position when they identify you if you're in class G; RAF controllers are not (may have changed with the 'harmonisation' of phraseology).
This happened to me when I was doing my qualifying XC; I was vectored all over the sky to miss military zones, then told to 'resume own navigation and cleared to en-route frequency' without being given a position or a QDM to my next turning point (of which I had informed them)
