I cannot imagine it being acceptable to post an application or whatever to 21 SAS and write on the envelope to '21st special air service regiment'...it would,i reckon,just be the name of the building or barracks or PO box or MOD and postcode.
Also 10 miles in an hour is nonsense as has been laid to rest many times on this site,by the end of pre-selection i would imagine most recruits could handle that but to start with its 8 miles over a good wee course in 64 mins or less-the ds will run faster than that but will tolerate if your slightly behind,they wont let you wear a watch either so forget timing yourself!
23 send you to cic-no idea about 21,sbs(r) need you to be already serving in a unit to transfer over to them.
I'll leave it at that as there is folk here know a lot more about 21 and 23 than me and will probably jump on me for even daring to reply to this thread.
KP.
