Keith, fair enough - BTW, the Armalite corporation maintain a fairly comprhensive web site - I think the rate of fire for an Armalite (bearing in mind this would be under ideal conditions with no time between changing clips at all) was somewhere around the 600-700 rounds per minute mark. Mind you although the Armalite is seen as the IRA weapon of choice they really have far more AK-47s in their armoury. It isn't so much that the IRA have no use for high rate of fire weapons as so much that they have tended to move away from direct gun to gun battles over the years. Estimates put their magazine at somewhere around the 1 to 2 million rounds mark - possibly a bit higher.
I think guerilla armies of the future may tend to move away from bombing also, in favour of more advanced forms of terrorism such as cyber-space attacks or similar. The Irish govt. had it's own computers attacked by parties unknown (strongly suspected to be Indonesian after the Irish complained about human rights abuses there) leading in them been completely non-functional for around 2 days afterwards.
