Fort Hood Medics Train in Underground Tunnels for Drone‑Era Battlefield Care

At Fort Hood, Texas, the Army’s 1st Medical Brigade of the III Armored Corps ran a large-scale exercise called Operation Silver Lightning from March 23 to April 1, shifting battlefield medical training into an underground tunnel complex to simulate mass‑casualty care under modern drone threats. About 300 soldiers and role players practiced evacuating and treating simulated wounded troops in the miles‑long decommissioned nuclear‑weapons tunnels, which were converted into a dispersed field hospital with triage, emergency rooms, operating rooms, veterinary care and clinics. Col. Kamil Sztalkoper said lessons from Ukraine’s drone‑saturated war mean traditional, sprawling tent hospitals spanning several acres can no longer safely operate above ground, forcing medics to learn to ‘disperse’ and ‘hide in plain sight’ in warehouses, buildings and underground facilities. Deputy commander and chief nurse Col. Brad Franklin described the scenario as deliberately stressing limited staffing and resources to force hard triage and reverse‑triage decisions similar to those faced in real operations. The inclusion of K‑9 teams and doctoral‑level veterinarians working on simulated injured military dogs underscores that the Army is trying to harden its entire medical system — human and animal — for contested large‑scale combat.
