a long time back i saw this programm on discovery... well come 2 think of it..... the programm was "extream machines" (EXMAC) where they had this episode on armour & stuff & they showed this guy who was (@ that time may be...) the most threatened president... and they showed an attempt on this guy, his armoured car was hit by a 1 or 2 RPG rounds 1 had gone straight through the engine, and even the inside of the car was messed up pretty bad (burnt & stuff), but the guy had escaped whithout any serious injuries..... guess wat they put in those really work..... if it can withstand a RPG hit.
but in a armoured car even if the tires r shot at they r able 2 go a certain distance whithout any probs....& the 1st areas they think of protecting when armouring the car is the most vulnerable areas like da tires, fuel tank, important valves, etc. thats pretty standard..... guess our guy's ordered our ones without those options..
