Allow Passengers to reload their weapons

Simple.

BE:
Scoop On the inside of the wheel well. When the tank drives crap gets shot into it from the tires/treds. Self assembling nanobots gather the dirt and extract metals and such. They then rapidly generate the amo.

NF:
Scoop on the inside of the wheel well. When the tank drives crap gets shot into it from the tires/treds. Bacteria soup in the scoop sorts the crap from the minerals and other needed things and rapidly generates the amo.

 

Man being able to generate pudding while driving would be pimp, you'd drive like five hours and then open the trunk and FIVE HUNDRED POUNDS OF PUDDING

 

They have nano-factories full of nanites creating different parts of the weapons in nanoseconds, then putting them together in a slightly bigger factory, then adding them to a magazine not in use.

NF soldiers jizz into the barrel of the cannon, close it, and it turns into a shell.

 

This. New general skill: Takes X seconds to urinate in the gun, and takes much longer to recharge, but gives you an entire full clip/one rocket for the weapon. Just need a good name and it's good to go.

I know you can implement this in a balanced and simple way.
...and make nf apcs have open hatch if you are there. :p ... *checking around for low flying items heading directly to him*
