To clarify, that would be me... the misspelling of Guderian was my mistake when I typed up the paragraph.

Also, in defence of Storr, his argument was not that armour or MBTs are not valid or useful. You are completely right that fixation on one system does not make a valid argument simply by extrapolation. I had simply taken one of his statements as I'm curious as to the subject and placed in on the board in isolation. A few paragraphs earlier Storr had written that "Anti-tank defence illustrates the need to take a systemic view of combat and armed forces." He makes the same point you do - just because scissors trumps paper in a certain situation doesn't mean you decide one is better than the other.

Thanks for the points, though.
