Fetball is really man power intensive. Ad like a single building can consume a whole battalion of troops. But you can also use the urban introstructure in quite clever ways. The british army talks about using cities as places where you might hunk down and hide. And that, i think, is a fascinating reversal of the old conventional wisdom that you never want to fight in cities. They're nothing but trouble. They'll absorb your army. We may have no choice. I wonder if it may be an opportunity, actually, to turn our adversaries technologicaladvantages against them. Then. This is the war of the future.
