Basically, everything apart from the armoured corps, the infantry regiments (actual troops on ground), Raf Reg and the CDOs (again troops on ground) are open to females. IIRC even the CDO artillery etc is open to women now? Anyone comment on that?
There are actually 2 branches in the RAF that women cannot join as regulars. The first is RAF Regt, in line with the prohibition on close combat arms (Inf, RAC but not, strangely, some elements of SF - see the lurid memoirs section of amazon.co.uk ). The second is Chaplain(RC) - but that is not strictly the RAF's 'fault'...
