What makes you think the M113 cannot keep up with the
Bionix???
If the M113 used is the Ultra version, then there is absolutely no
problem whatsoever. In any case, there is no need for an air
defense vehicle to be directly in line with the Bionix. Their role
will be to support from behind, at the rear echelon.
BTW, I have experienced the old M113 before back in NS, and believe
me, in the hands of a "garang" driver, it can give you a hell of a
ride!!!!!!
My M113 driver can even do drifting....
