Supplies should be ammo only. Jeeps should be able to roll themselves back over on their wheels; everything else should just die.
Also, GVs should burn gas, and they should also catch fire. Then, the wittle guys should be able to bail out, but they should also catch on fire sometimes when they try. Then, I want to be able to shoot them in the legs, and let them roast, without them being able to do that gamey towering out thing before they're good and dead. WTF, is this Barbie's Horse Adventure?
