Most nations have some kind of commando unit, usually a hundred or so specially selected and trained troops. Often, the British or American commando units (SAS/SBS, Special Forces) are called in to conduct training and create a commando capability for some countries. As a general rule, the larger the nations armed forces, the more likely they are to maintain a useful commando force. This is because the commandos are usually recruited from people already in the military. Leaders for commando units are selected from those who have served in the commandos. The smaller commando forces in most nations tend to vary quite a bit in quality, depending on how good the current leadership. Larger nations have a larger pool of troops to select from and thus are able to maintain quality in their commandos. But in many smaller nations, the local commandos are, at best, a SWAT team with fancy equipment than capability. Thus the following list is not exhaustive.
Argentina has some anti-terrorist units and special units to deal with criminal gangs. Some of these men are trained to commando standards, but they are primarily intended for police work in Argentina. There are two commando companies.
Austria formed the Gendarmerieeinsatzkommando (Police Special Command or GEK) Cobra in 1978 in response to growing terrorist acts within Austria. A very well trained and equipped, but small, organization that only operates within Austria.
Australia has their own SAS (Special Air Service) commandos, including a platoon who can operate from the sea (like U.S. Navy SEALs). Australian SAS have a close relationship with U.S. Special Forces and SEALs. The Australian forces consist of the 1st SAS Regiment (500-600 active duty and reserve troops), 1st Commando Group (about 250 troops) and the 4th Royal Australian Regiment (several hundred commandos) and several companies of LRRPs.
Belgium came out of World War II with a battalion of commandos who had trained and operated with British commandos. The commando tradition continues, with a Para-Commando regiment and some LRRP units.
Canada formed Joint Task Force Two as an anti-terrorism commando unit in 1993. Has a strength of about 200 men.
China has formed two "Special Warfare Groups" that are trained for commando type operations. Little is known about them, but they involve several thousand troops.
Finland has a long tradition of commando type operations. They currently have 400 troops in Ranger Warfare Companies. These men perform LRRP duties and commando type raids. There is also a battalion of paratroopers trained for Special Forces type work, mainly behind enemy lines (ie, in Russia) if there should be another war. There is also a 40 man Bear Force for hostage rescue work.
France has several elite combat units, but only one, the 1st Para-Commando Regiment (about 300 troops) that are of commando quality. These troops are the same quality as the SAS or U.S. Special Forces. The French armed forces also have a number of support units for their commandos (special helicopters and the like.)
Germany's KSK (Kommando Spezialkraefte, or "Special Commando Force"), was created in 1994 and became operational in 1997, is getting it's first combat experience in Afghanistan. About a hundred KSK troops are in Afghanistan, and more are expected. The KSK were modeled on the British SAS and U.S. Special Forces. The unit was formed after 11 German citizens were trapped in Rwanda in 1994 and it was realized that there was no German military unit available to rescue them from chaos then existing in Rwanda. By 2000, KSK had about a thousand members. Recruits were drawn from existing airborne units and British SAS advisors helped devise the training program. Since the unit was officially formed on April 1, 1996, they are nicknamed "the Jokers." It is not known if anyone used the phrase "send in the clowns" when KSK was ordered to Afghanistan. In addition to KSK, there are also three companies of LRRPs and a counter-terrorism unit (GSG-9, about 250 troops.)
India first formed a commando force, composed largely of Tibetan exiles, after getting the worst of it in a 1962 border war with China. As relations improved with China over the years, the "Special Frontier Force" (SFF) switched from its original mission of stirring up guerilla operations inside China, to counter-terrorism. Size (about 10,000 troops) and organization (six battalions, each of six 123 man companies plus a headquarters) of the units has not changed much in 40 years. Training is still rigorous, but there are fewer Tibetans in the unit now. There is also a Para-commando battalion, used as a quick reaction force. A small (about a hundred men) National Security Guards force is organized and trained to deal with hostage situations. A very competent outfit. There are 1200 Marine Commandos, who sought assistance from British Royal Marine Commandos and U.S. SEALs to set up their two year training program.
Israel has a large force of commando troops for a country its size. There are two small battalions of Arabic speaking troops used for undercover operations and raids into the Occupied (Palestinian) territories). Sayeret Shimshon (Unit 367) is assigned to the Gaza Strip, while Sayeret Duvdevan (Unit 217) takes care of the West Bank. There are four companies of Ranger type troops (Palsar) that normally each support one of the four elite infantry brigades of the army, and two more to support armored brigades. There are also three LRRP companies (Special Command Teams), with one assigned to each of the army's corps headquarters. Lotar Eilat and Unit Yamam are two hostage rescue units (each under 100 troops.) These units are also used as commandos (as when there is a lot of violence with the Palestinians.) There are also several hundred highly trained LRRP troops assigned directly to intelligence units. The navy has a SEAL unit (Shayetet 13) of about 400 men. This unit is more selective than the other commando units, with about 80 percent of it's candidates failing the training course, compared to about 50 percent with other units. The navy also has a company size unit of divers (similar to U.S. UDT). The police force also has over a thousand specially trained men who are a cut above your usual SWAT teams.

And if you want to go on about the Royal Marines as a whole you're going to have to mention the RAF Regiment and Paras, which are to a much higher standard than reg grunts. But then you're going off a tangent and wasting time...
