Expired hydraulic fluid sits in a storage locker at the Hazmart on Barksdale Air Force Base, La., Dec. 12, 2017.

Critical assets are defined as aircraft or lifesaving equipment and subsystems. Tactical assets are defined as weapons and its subsystems. (U.S. Air Force photo by Airman 1st Class Tessa B. Corrick)
