Personally I never provided a fighting position for, or supported anyone. I was too busy driving in and out of them and charging with my M-1, and all the Grunt types (who these days are, and for some time now have been, wanna-be tankers, playing dress up in CVC's and Nomex in their cute little Bradleys) have always followed us through the breach, and in fact always caused us to go slow so they can keep up.
