Tricky one. Would you let all ex servicemen in unescorted? Some oik signs on for a few years then becomes radicalised after leaving.....and I'm sure you could think of other potential scenarios. At the famous Hants Heli Base (back in line AAC!) it was, until relatively recently, possible to walk onto the base from across the MQs outside the wire. The IRA missed a trick there I feel. I think those currently serving are entitled to good security, and if that inconveniences us retirees, well I won't be complaining.
