US Army practices digging mass graves for fallen troops amid looming war threat

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.

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 fatality management NCO for the 3rd CSC, said in a statement: 'This exercise allowed us to take a critical look at how we respect, honor, and systematically manage our fallen in a high-intensity conflict.'If we went to war tomorrow, we would be making this up as we went along. What we are doing here is taking a scientific, field-tested approach so that we can maintain positive control and respectfully care for our fallen.' The tests exposed a mismatch between the Army’s existing burial guidelines and the size of its modern machinery.Instructions called for a seven-foot corridor between trenches, which proved two feet too narrow for bulldozers to pass through without disturbing the burial area.Crews expanded the trenches to 15 feet wide and left nine feet of undisturbed soil between them, giving the machines enough room to maneuver. 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. Above is a soldier measuring the trenchWhen teams later uncovered the model skeletons and water containers, they found both had survived without being crushed, suggesting the technique could help preserve remains for identification.Engineers said soil conditions would also affect the process, with dry sand, frozen ground, clay and mud presenting different challenges.1st Lt Connor Thompson, an engineer officer with the 27th Engineer Battalion, said: ‘Getting our operators actual stick time on this specific task gives us data rather than assumptions.'The measurements and findings will help update Army guidance to ensure burial layouts accommodate modern equipment.A further exercise planned for next spring will test the process during daylight and blackout conditions using night-vision systems.Army chaplains and religious affairs personnel also rehearsed their roles in temporary battlefield burials for the first time in more than 20 years.For much of the past two decades, troops killed during counterinsurgency operations were quickly transported back to the US through established military mortuary systems.The exercise explored how to honor fallen soldiers during a larger war, when intense fighting could prevent their immediate return home and leave little time for individual funeral services. Lt Col Ruska, chaplain for the 3rd Corps Sustainment Command, said: ‘In a high-intensity, contested combat environment, fatality management teams cannot stop a 24-hour interment operation for individualized religious gravesite services.'Chaplains identified a need for clear procedures to provide religious support during these burials while allowing crews to continue working around the clock.Before digging began, Maj Warwick Fuller, chaplain for the 20th Engineer Brigade, offered a prayer to consecrate the burial site.Ruska said battlefield conditions could make it impossible to immediately establish a fallen soldier’s identity or religion. Chaplains consulted representatives of faith groups with fewer members in the military about how to handle those circumstances. To test whether soil weight could crush human remains, the team placed model skeletons and sealed water containers (pictured) at the bottom of a trench before filling it inThey agreed that consecrating the ground before burial could help reassure families that their loved ones were treated with dignity, even when individual memorial ceremonies were not possible.Master Sgts. Amelia Alston and Lakesha Copeland led efforts to incorporate religious affairs specialists into the burial process, including coordinating logistics, supporting troops and helping ensure respectful treatment of the remains.After the simulated remains were lowered into the trenches, Maj. Cornelius Muasa and Capt. David Chacko offered committal prayers as engineers covered them with soil.The training also highlighted the strain on personnel tasked with caring for the dead. Army planning estimates indicate that religious support teams handling heavy casualties could experience physical, emotional and spiritual exhaustion within four to six hours.The findings underscored the need to rotate teams regularly so they could continue supporting troops throughout prolonged burial operations.
