Grafenwoehr, Germany A section of the U.S. Army's largest training base in Europe was closed off after WWII-era rifle grenades were discovered by workers digging a trench near a building. A tweet from U.S. Army Garrison Bavaria announced that UXO had been found near Building 541 at Grafenwoehr's Tower Barracks and advised people to stay away from the area until further notice.
According to Don Wrenn, a USAG Bavaria spokesman, "One of the buildings in the area is under renovation and a trench was being dug in the area in conjunction with this when the (ordnance) was found." The four rifle grenades were safely removed from the site, Wrenn said.
Rifle grenades were used by many combatants in WWII to fill a tactical gap between hand grenades and mortars. They were also frequently used by infantry as an anti-tank weapon.
