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. https://www.youtube.com/watch?v=i9H50tHiHjs The MOAB — 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. For comparison to the 21,000-pound MOAB, each Tomahawk cruise missile launched at Syria last week was 1,000-pounds each. The statement said U.S. forces took every precaution to avoid civilian casualties. [Fox News]
