SHRAIL. Conceived by two US Army surgeons, Capt. Maxwell Sirkin and Col. Jason Hiles, the lightweight Sirkin-Hiles Rail System (SHRAIL) rail system mounts to a standard NATO litter to transform it into a highly-functional operating table or intensive-care-unit bed. The rails provide a standardized means of attaching a broad range of medical devices, monitors, and products. Courtesy of US Army
