Lets Quash Some Myths
First of all the RAF Civil Component Commission still exists but is closed to new entrants. So whatever Top Cover thinks he's joining it ain't that.
The comment about Met men refers to the Mobile Met Unit who are not RAFVR but Sponsored Reserves in the RAFR. And yes this means they have to pass all the usual nause: they go through basic reeserve recruit training at Halton and if applicable reserve officer training at Crawnell. Once in they have the same liability for CCS etc.
Still intrigued as to just what Top Cover thinks he's getting in to though.
