You know, as far as the "shoot, move and communicate" quickly issue goes, my experience has been completely opposite.
When I was a young mortarman in an Armor BN (hating life, the army, and tanker boots) I saw tanker "quick thinking" on more than one occasion. Every time we did a maneuver exercise as a Battalion, the tankers killed everyone. I'm not talking enemy. They killed the BC, the medics, the scouts, the mortars, the support platoon, etc. You name it. If it wasn't in a fucking Abrams, it was toast.
Truly, I have never seen anything remotely like that since I left that world and came home to the infantry.
And I'd rather be poked in the eye with a sharp, flaming stick than ever go back to an Armor or Cav unit again.
