not have the same maintenance, spares and cross country speed; unless
are all the same weight. Cross country speed is a combination of the
of power-to-wieght and sprung weight to unsprung weight. An APC on an
running gear, that does not have the same armor, will need to have a
suspension. Most of the weight difference between the APC and MBT is in
sprung portion of the vehicle. Even with the lighter springs and shock
absorbers, the unsprung weight is mostly the same. A major drop in
sprung/unsprung weight limits speed by reducing the speed at which going
along the non-level surface is easily confused with tumbling down a
end over end.
If you compare a mid-70's american land yacht to what now passes for
luxurious comfort, it takes a very complicated adaptive suspension to
the same level of comfort as a massive curb weight.
