Lol makes a change me not agreeing with ZZ
hi m8
I will agree however that for the SAS to have been any use, they would have had to been called in very early to the situation.
But i thought id drop by and give some facts
Since 1970 the SAS as Actively worked in anti terrorism, the wing is better known as the CRW wing (Counter Revolutionary Warfare ).
Not sure how it worked in the early years but recently ie last 20 years, each squadron takes it in turns to act as the anti terrorist teams for the crw wing. (4 squadrons )
With that said the crw wing as at their disposal aprox 64 men per squadron, and thats not counting the spooks and siggies attached to the sqn. (Sqn comprises of 4 troops , troop is 4 x 4 men teams), also if it was required they could have sent a second sqn making it 128 of the most highly trained combatants in the world......my point ? there was enough numbers to attempt the siege.
Now the discussion about who is best

im from the UK so slightly biased

But i will say in the last 20 years the SAS as been the most active military unit in counter terrorism, therefore making them the most experienced.
Wether the SAS could have done better in russia? I say yes, but that doesnt mean there wouldnt have been casualties. It was a difficult situation, and from the reports i have read, i think there was going to be inevitable casualties.
