So the question then, would be just how fast does someone have to be
moving in order to achieve those particular velocities with both a running
speed component plus an assist that is "reasonable".  If I had to
"imagine" such an assist, I would presume it wasn't just legs that were
involved per se, but also jet units (or rocket for that matter) at verious
other locations for purposes of stability.  I would imagine too, that the
computer has to be involved in keeping the suit stable throughout its jump
as well as its landing aspects.

If assuming a battlesuit can move say, 30 mph on open ground while
running, how much extra assist would be required to attain the jump assist
aspect - or is it literally impossible to handle with GURPS VEHICLES?
