& a Divison is like a Regiment with extra Platoons, is it?
From what I understand, after current spending cuts, future UK "divisions" will be more like light infantry battalions, with - if they are lucky - an attached platoon or two of specialists. These would comprise important backup such as:
artillery support (a chap with a radio to the nearest US unit);
armoured recce (two chaps wearing lots of body armour in a fast car);
engineers (several chaps with hammers and nails);
field barber shop (a chap with scissors and another chap with a mirror); and
combat bath 'n shower section (chap with a hose).
There again, thinks could be worse. For that - look at the current state of the RN....
