We took down Iraq in about two weeks with an air-land force of armor and aviation. Not bad for an obsolete weapon. Tanks are not obsolete. Nor are air forces.
WWII proved that alternative usage of industry is a benefit that can be realized in a matter of months and a little retooling. That principle is just as valid today.
Information is itself not combat force; it is a force multiplier. There’s a difference. The only way your computer can itself kill me is if you pick it up and hit me in the head with it.
You prove my point. The outcome of this battle did not turn on a slugfest between tanks, with the side who could produce more winning.
