RE: Flamethrower???
Totally immaterial whether you are in a tank or cave...a flame thrower is a weapon which burns away all oxygen and sufficates the enemy...a tank will be equally effected by this alone....followed by searing heat and fire. Breathing when a flame thrower hits, will instantly burn out the lungs and armor and NBC gear is totally useless against a flame gun. Doing away with the human crew leaves the tank pretty useless. It's one of the most horrible weapons ever devised and the only defense is to take it out before before it gets close to you.
RCDude, your reasoning is very flawed and imature. What you need to see are photos of a tank that has been hit with napalm or a flame gun. NOT pretty at all.
