Air Level Monitor Army Spc. Timothy Sparks, a diver with the 7th Engineer Dive Detachment, monitors the air levels of two divers during an underwater recovery mission near Nha Trang, Vietnam, March 20, 2018. Divers plunged 80 feet to the sea floor and spent about an hour dredging sediment, which was then screened for human remains and material evidence that could lead to the identification of missing American service members.
