Since you are in the UK, you may not be aware of how heavily armed many parts of the US happen to be. Churchill said “We will fight them in the hills, in the fields, and on the landing grounds”. I suspect that the UK no longer has a serious ability to do that. The US can.
Do they have gear capable of taking down helicopter gunships, fighter-bombers and tanks, or just small arms?
The government also has technology that can detect the trajectory of home-made mortars and is getting better at detecting IEDs, and now detecting snipers before they can even fire a shot.
As the insurgencies in Afghanistan and Iraq have shown, you can’t hope to defeat a western military, the best you can hope to do is survive....
