I haven't thought of a way to properly implement this in game yet but I was thinking of being able to destroy tanks with molotov cocktails and being able to even physically get on a tank, and be able to throw a grenade into the hatch. Maybe on a tank that's disabled. Maybe even when you're close enough to touch a tank, be able to stick your grenade into the treads to maybe a 20% chance of disabling it. Something along that idea.
