I can't even believe I'm entering into this foray.
First of all, GSG9(Grenzschutzgruppe-9) and GIGN(Groupe d'Intervention de la Gendarmerie Nationale) are both police counterterrorism teams similar to US SWAT teams, although the comparison even there is small. I would really only compare both of those groups to the relatively small number of full-time US SWAT Teams.
USN SEAL's (SeaAirLand) and British and Aussie SAS (Special Air Service) are military units consisting of several small, specially trained groups.
I'm definitely not trying to pick a fight, but I am not surprised by the reaction of Henry the V, a US Marine, to throw Force Recon out there. Once a Marine, always a Marine.

The US Army also has Delta, Special Forces (Green Berets) and the Army Rangers. The US Air Force has Pararescue. Virtually every unit within the US Military has specialized units of some sort. Hell, Poland has GROM (Grupa Reagowania Operacyjno Mobilnego), Russia has the SPETSNAZ GRU (Special Forces of the Main Intelligence Department of the General Staff of the Russian Army)
The Israelis actually have many special services, all specialized units bearing different name and numerical designations. Their infantry/reconnaisance units are called Sayerets, and I believe that there are four of them out of different bases. They also have an undercover IDF SF unit that operates in the occupied territories. The Israeli military structure is relatively complex, well, at least for someone not from Israel, but their military is considered one of the best in the world. And I'm not getting into a political debate here, just strictly military expertise.
My whole point in this is that each of these units are very capable, very specialized, units, who are deployed to different areas of the globe, for relatively specific missions. They cannot be compared. The whole "my team can kick your team's ass" is pointless, although unit rivalries definitely serve to boost morale, and sense of esprit-de-corps. In fact, most of the special forces units throughout the US and throughout the world often conduct training exercises together and have served alongside each other in numerous conflicts. All are professionals and specialists in what they do, but many serve different purposes dependent upon the situation.
While true that Force Recon in the Marine Corps is a formidable force, and tried and true professionals with what they do, they serve an entirely different function than Rangers, who are specifically battalion sized elements of light infantry. (Instead of a company of Force Recon within a USMC battalion, they are a battalion sized element, not serving in a separate brigade) Not better, not worse, different.
US Army Special Forces, a longtime favorite of President John F. Kennedy, serve an ENTIRELY different purpose. Whereas a USMC or Army Ranger Unit may contain teams of soldiers, those soldiers are primarily younger, lower ranking soldiers, with NCO's and Officers of higher rank supervising, in a normal military structure. In Special Forces, or at least in the active detachments, or assigned to A -Teams, are all NonComissioned Officers, with generally one commissioned officer assigned to the team. All have a fair amount of military experience already, and all are highly trained specialists within the team, with their own series of MOS' (military occupational specialties - the 18 series). They also each have one member trained in freefall and another in combat diving. They have 5 primary missions: Foreign Internal Defense, Unconventional Warfare, Counterterrorism, Reconnaissance and Direct Action. Under the scope of these missions, they also have a separate primary mission, and generally train other armies, diplomatic factions, and train in humanitarian and civic action programs in other friendly countries.
So, Henry, I hope I didn't offend you in any way, my whole point is that comparison is pointless. I appreciate your service, and I would not argue the fact that the USMC is one of the best fighting units in the world. But in all honesty, no one group, branch of service is really better than another, they are all impressive groups of volunteers, and trained professionals. And that includes GSG9 and GIGN, and every variation of Special Weapons and Tactics or Counterterrorism squads throughout the world.
Whew! Sorry to go off on a rant.
