Mother of All Bombs
Before the first Gulf War, Saddam Hussein promised the Mother of All Battles if the US interfered with his conquest of Kuwait. Since he had more firepower under his control than Germany did in WWII, he felt confident in this claim. However, he did not realize how advanced the US military had become and Saddam's vaunted military might was quickly demolished by the US and its allies.

The US military has continued to improve its technology and yesterday it tested a 21,000 pound bomb, a larger version of the daisy-cutter used in Vietnam and Afghanistan. It is the largest conventional (non-nuclear) weapon in the world. It belongs to the MOAB class of bombs. Officially, the acronym stands for Massive Ordnance Air Burst. In a not-so-subtle reference to Saddam's vain boast, our soldiers are unofficially calling it the mother of all bombs. One of the many uses for this type of bomb is to destroy secured bunkers - and it can be dropped by bombers flying well above the range of any anti-aircraft weapons Saddam may posses.

The Miami Herald has a video of the bomb's test available. If you watch it, keep in mind that the explosion is filmed from about 12 miles away.
