Excellen. One of my most favourite areas in the world. Brits have SAS (The BEST IMHO), + SBS( Special Boat Squadron). We Aussies and the Kiwis also have SAS, NOT F*****G DINGOS!!!!!!!, and they are among the very best fighting men in the world.
Foreign Legion 2 REP do operate in a semi-special forces/counter terrorist role, but French also have some other units, including Frogman and combat divers ( hmm.. Rainbow Warrior.....)as well as paramilitary types attached to their foreign intelligence wing, the DGSE.
Geramny has the GSG9, not strictly military as they are part of the Federal Border Police, but very famous as counter terrorists. They were established aftyert the Munich 72 icident, as most of u would know. They did the job at Mogadishu in 1977(?Will check)
Russians/Soviets have Spetznaz as already mentioned. They differ from other special forces because of doctrinal differences and their role etc. There was a BBC documentary that, although sensationalist and partisan, provides a starting point, as does books by the GRU defector Victor Suvorov(recommended for insight, albeit biased, into Soviet military). They did a job in Beirut in early 1980s to free captured KGB- cut off heads of kidnappers relatives. Brutal but effective.
Israeli special forces are very, very good, and is hard to find stuff on them,but there are some references(see end of post)
Most secretive of them all is "The Unit", or the Sayeret Matkal. Very good soldiers, and Ehud Barak was their ex commander.
Mossad do have some "agents" who could be seen as spec forces, but their "Katsas" or case officers mainly do intell work rather than "wet work".
This is an area of immense interest to me, and one I am writing a text about, in addition to my thesis, which is on intelligence. There are quite a few sites that have quality info, so I will list a few:
www.isayeret.com/main/menu.htm
www.specwarnet.com
www.specialoperations.com
Or just look for "Special Forces" or "Counter Terrorism" in a search engine.
P.S. They need Special Forces in Civ2, Civ3 or Civ4 or whatever. Just put em in or create the units. They rock, and in real life do a difficult and dangerous job with an enormous degree of honour, professionalism, and elan.
