I'll have you know the SA80 is now pretty decent, granted, it's been redesigned for us by the Germans though ...

A lot of the issue, especially with things like the Snatch, is that they were designed to get around quickly, hence minimal armour, but in modern theatre of war against insurgents planting IED's it breaks down totally.

Same issue with the Eurofighter Typhoon - great A2A, but awful for what's needed now, with is A2G.
