Saddam Hussein's Boongke

Saddam Hussein, Iraq's President from 1979 - 2003, has a series of bunkers built in the case of bombing. It is known that Saddam Hussein's largest and most solid bunker is coded 2000 and is about the size of a football field.

This boongke can withstand "large scale" bombardments like 2,000kg of TNT.

Inside the bunker, there is enough food and utensils needed for up to 50 people for a period of 6 months . The 2000 bkeke and the remaining bunkers with the symbols "Zero", "P" and "C" can be resisted. Fight with "large scale" bombardments like 2,000kg TNT or a nuclear bomb from a distance of 2km. These bunkers have air filtration systems and escape routes in case the main door is blocked. These emergency doors can only be opened from the inside.

If you want to use rockets to pierce the bunker, the missile must work from a 90-degree angle to be effective. But first, it needs to penetrate the bunker protection classes. However, the impact angle of missiles and successive successive shots is a "impossible mission".
