Hey guys
Just been reading through your posts, and I would like to add my own 2cents. Please forgive me if I come across as naive or arrogant - please bitch me as much as you like if I do
Basically, we have the Special Forces, very small in size, normally sent in first to secure very important objectives, accomplish important task that no conventional force can do, and collect information on the enemy. Could not take on any large conventional force! SFs are able to sustain themselves for long periods of time.
Then there are the commandos, medium size (could take on a medium sized army, but doubtful that it could take on a large conventional force), normally used as a spearhead force, they are able to do many of the tasks normally assigned to Special Forces and just about all jobs assigned to Army infrantrymen. Commandos are able to sustain themselves for short periods of time.
Now for the Army, it is considered a large conventional force, being that it has plenty of bodies to through at the men - not literally, but you get the point

The Army is very rarely used for specialists tasks due to the size and is normally used to take on or hold off other large conventional forces. Most Armies need to be sustained constantly, otherwise they will lose strengh quite quickly.
As for the Paras, they can be considered standard infrantrymen, because unless there is a WW3 and there is a need to send a large conventional force behind enemy lines, the Commandos can pretty much do the job - no disrespect to the Paras, but they are the facts! However, although the Paras can be considered a conventional force, they are able to accomplish some specialists tasks and able to sustain themselves for short periods of time, when necessary. Mainly used to take strategic points and hold against another medium to large sized conventional force.
For any General, all the above are needed, including the Navy and RAF, because in any war scenario, you will need specialists forces and large conventional forces.
I know the descriptions are very brief, but I'm sure any intellectual person gets the point I am trying to make. Each unit has been designed for a certain task, and in many cases, can only be compared as above.
Thanks all
