I stand corrected on the GR4s and am happy to admit it. Not that I ever saw them when I was flying in, around and between Basrah and Al-Amarah.
I am temporarily resident at the big Purple Learning Centre in Swindonshire, and we have been discussing this exact attitude displayed by the Army. ie: they don't know, or even give a t0ss, about air power unless it's directly over their heads or taking them home.
'Joint' begins with 'A' and ends in 'rmy'
