just a suggestion, make a rear door hatch, like the apc's in real life

then make it have tracks, instead of wheels,

then have and intergrated mine burial device

gun ports, lots of them

a 50 cal styled gun mount on the roof, with a
tippmann 98 enclosed in releastic 50cal shroud, with egrip,laser, and
flatline, and 2000 round box mag under the gun

turbocharge, and a train horn
360 degree fog lights
spotlights
and r/c helicopter uav landing dock

that would be my wet dream
