Commando <!> "Special Forces"
Since ALL Royal Marine Commandos can do all the jobs (allegedly) performed by the American Special Forces, and even the average British squaddie has to be capable of doing most - if not all - the tasks assigned to American "highly-trained" troops (ie the US Army's Rangers), I guess you could say that the term "Commando" is no longer an indication of fightin' men trained to a greater degree than their fellows.
Of course, if the Labour government hadn't ripped the heart out of our Armed Forces (or perhaps Armed FARCES will become more apt, if Labour carry on with the current rate of cuts...) and they still had enough people and equipment to actually do the tasks assigned to them by pencil-necked REMFs sitting in nice cosy offices without having to push themselves and their kit well beyond designed usage then maybe we would still have enough Regiments to have "special forces" units in addition to the standard line units.
Isn't it strange how the Labour Party in opposition castigasted the Tories "Options for Change" defence cuts as being too harsh - but as soon as they got into power they went and cut the budget down even further, and still have to keep cutting regiments, fleets and squadrons but still cannot balance the books...
