CNN broke the story Thursday afternoon that the U.S. has dropped the largest non-nuclear bomb ever used in combat on an underground ISIS compound in Eastern Afghanistan. The GBU-43 Massive Ordnance Air Blast device (MOAB) is popularly known as the "Mother Of All Bombs." It can have a blast radius of up to a mile. The weapon has been in service since 2002 but has never yet been used.
The targeted ISIS compound in Nangarhar province is very close to the area where a U.S. servicemember was killed in a firefight Saturday.
