In a battle between a U.S. Navy SEAL tema (i.e. 120 men) against a comparatively-sized force of British SAS, who would emerge the victor? Both are armed and equipped in their respective fashion and the battle takes place in... well, wherever.
Baised on research I have done, there aren't even 100 SAS Soilders
so if you got an even match going X# of SEALs vs X# of SAS
here's what you would expect
Well the SAS is divided into to four Troops: (Primarily ways of insertion)
Air Troop
Boat Troop
Mobility Troop
Mountain Troop
The SEALs are broken up into SEAL Teams, but they do not differ much
Each Seal however is trained for insertion by Air Sea and Land
Off the bat the SAS would have the advantage
SAS soilders are specialy qualified in one area(but are trained in all)
SAS would have more specificly qualified men for the insertion part of the attack
The SAS could then set up their Machine guns and mortars
and the SEALs would not be far behind
but since the SAS already have their mortars set up they would be one the ones favored to win
but all things considered
any soilder in any special forces regiment is not a... super infantryman(yes they must be a good infantry soilder, but elite regiments like the SAS don't carry out infantry assignments)they carry out more sensitive ones (such as hostage rescue, snatch and goes, recon, ect.)
these guys don't go in kill 'em all and get out
they go in swift, do there job, and get out before anyone knows what happened
