[FoxNews] The U.S. military dropped the largest non-nuclear bomb in eastern Afghanistan on Thursday just days after a Green Beret was killed fighting ISIS there, a U.S. defense official confirmed to Fox News.The GBU-43B, a 21,000-pound conventional bomb, was dropped on an ISIS tunnel complex in Nangarhar Province.
The MAOB -- Massive Ordinance Air Blast -- is also known as the "Mother Of All bombs." It was first tested in 2003, but hadn't been used before Thursday.
"As [ISIS'] losses have mounted, they are using IEDs, bunkers and tunnels to thicken their defense," Gen. John Nicholson, Commander of U.S. Forces in Afghanistan, said in a statement. "This is the right munition to reduce these obstacles and maintain the momentum of our offensive against [ISIS]."
For comparison, each Tomahawk cruise missile launched at Syria last week was 1,000-pounds each.
