An amusing little story Richard but that is all it is - a story.

Unfortunately lots of ex-Navy members on this forum will be able to poke holes in it.

1: Passing-Out Parades are just that no branch of the Royal Navy puts on demonstrations to entertain the crowd

2: "When he cam out of the Glasshouse, the Navy said"??

No such thing as "the Glasshouse" in the Navy - it's DQ's, and given the circumstances as you describe them the charge would have been "Attempted Murder"

3: "he spent the next few years killing the enemies of her maj mostly hand to hand in covert things as part of the SBS"

So straight out of basic training, without a single SQ he is set to work as a Naval Rating (Ordinary Seaman at this stage) killing people as part of the SBS. If there is anybody reading this down in Poole they will be pissing themselves with laughter. For your Walter Mitty to have done any of this he would have had to have gone through the following:

- Basic Commando Training at CTCRM Lympstone (by the sounds of your boys behaviour he would not have lasted one week);

- Served between 2 to 4 years in a Royal Marine Commando Rifle Company with either 40, 42 or 45 Commando Royal Marines, and in that time be recommended for selection for Special Forces. (Your boys penchant for bucking the system would not be the way to get that recommendation);

- The SBS do not carry odds and sods passengers all have to be qualified as Royal Marines Commandos (A Royal Marine Commando can be a member of the SAS, an SAS Trooper on the otherhand cannot transfer and just join the Royal Marines);

- Very rarely are SBS assigned jobs where they "kill people" hand-to-hand or otherwise, they tend to be used to gather information on targets and pass that information back for action by others. If the SBS and the SAS do their jobs properly you as the enemy will never know that they have been there. The first you will know that something is amiss will be the moment you die.
