- The US Army has started practicing digging mass graves to bury fallen troops for the first time in decades amid fears of a looming war with Iran. The exercise tested how effectively diggers and excavators could help keep bodies intact pending identification and return to the US. Images of the training captured an Army D6 bulldozer pulling dirt from the ground to form massive trenches. Operators kept the bulldozer blade 18 inches above the ground, allowing loose soil to fall into the trench instead of forcing it down. To test whether soil weight could crush human remains, the team placed model skeletons and sealed water containers at the bottom of a trench before filling it in. After crews dug a trench in an hour and 15 minutes, planners estimated that an engineering company with eight bulldozers and four military excavators could dig and fill enough trenches to bury up to 2,400 bodies a day, working around the clock. The US Army said in a statement: 'The exercise served as a critical test of concept to validate the feasibility of battlefield temporary interment, an operational reality the US Army has not executed at scale since the Korean War.' Nearly 37,000 US personnel were killed in the war from 1950 to 1953. The training comes as America's top Middle East commander, Admiral Brad Cooper, has reportedly briefed President Donald Trump on attack options to resume the war in Iran. Trump is weighing up options to resume attacks on Iran. The meeting reportedly included cabinet members and covered considerations on continuing the US blockade in the region. Army training participants included troops from the 3rd Corps Sustainment Command and the 20th Engineer Brigade at Fort Bragg, North Carolina, along with military chaplains and other religious support personnel. While it occurred on October 22, news of the drill just reached the public, who raised concerns about the motive amid a time of potential war. Sgt 1st Class Delbert Ruede, the senior fatalit
