Vash dove out of the way, but swung around a moment later and one-two-three'd it up next to the cockpit, hanging on one of the support bars as they crashed through. The machine barely paused a second over crushing the wooden doors (they hadn't opened them enough, apparently- not that Vash had known they were supposed to be open), though it did get a bit bumpy rolling over them. And the sound of snapping wood? Not that fun to a Plant's ears.
.... Wait. Len'd only watched someone else drive one?
"Do you know what all the levers do?!" There were plenty of them, as he saw it through the glass pane, red coat trailing in the wake and always keeping one eye out for snipers, even if they were pretty far from the battlezone and he was busy making sure they didn't, well, crash into something that could actually... fall on them. That was sort of a big problem. - No, wait. They were headed for other construction equipment, and he didn't know if Len could stop. Vash held on tighter to the bar, edging over to the doorway. Ready to just snag Len's shirt and jump away -- not that they were moving that fast, but it sure felt fast when you were in something like a real-life obstacle coarse.
