Luckily the grenades can not be safely used without a proprietary grenade launcher.
Via the Washington Post:
The Air Force is offering $5,000 for leads on the whereabouts of a box of explosive grenade rounds that its personnel accidentally dropped on a road in North Dakota while traveling between two intercontinental ballistic missile sites — the facilities scattered across the U.S. heartland that stand ready to launch nuclear warheads at a moment's notice.
Airmen from the 91st Missile Wing Security Forces team were traveling on gravel roads May 1 in North Dakota when the back hatch of their vehicle opened and a container filled with the explosive ammunition fell out, according to a statement from Minot Air Force Base.
On May 11, the Air Force sent more than 100 airmen to walk the entire six-mile route where the grenades were probably lost, according to a statement from the local Mountrail County sheriff. But two weeks after it was lost, the box of explosives still hasn't been found.
The missing ordnance is a belt of linked grenades for the MK 19 automatic grenade launcher, Sheriff Kenneth G. Halvorson said in the statement shared with The Washington Post. "This ammunition is specific to that launcher and will not operate in any other launching device without catastrophic failure," he said.
