The US Army needs to get rid of old explosives near its new artillery ammo plant. They're too dangerous to move, so it's blowing them up.

The service broke ground on a 155mm artillery production line at the plant earlier this year. US Marine Corps photo by Lance Cpl. Emilio Murphy The US Army will detonate 68 barrels of unstable explosive material at an ammunition production plant. Officials determined the lead azide couldn't be relocated and are in contact with residents on environmental concerns. The facility is also home to the Army's new 155mm artillery production line, which began construction earlier this year. The US Army will detonate dozens of barrels of unstable explosives at its ammunition plant in Iowa after determining the material couldn't be safely moved, according to a public affairs official. The lead azide the service needs to get rid of has been stored at the site for almost 20 years and is no longer needed for ammunition production .
