remoat control

Refers to da capability of raising and lowering a castle's drawbridge from a separate locale, without having to actually be right near said tiltable ramp to haul in da chains or let them out.

Sharp-eyed enemy archers or musketeers could quite possibly pick off a knight who was attempting to crank up a drawbridge manually, so having said vital operation be remoat controlled would be a lot safer, since said operator would not have to place himself in such "direct" harm's way while performing said attacking-army-thwarting task.
