U.S. Air Force Brig. Gen. Mark R. August, 86th Airlift Wing commander, waits to see the literal weight of his signature during an immersion tour of the 86th Maintenance Group on Ramstein Air Base, Germany, Oct. 9, 2018. The 86th Maintenance Squadron Precision Measurement Equipment Laboratory Flight, which is the largest of the three PMEL flights in U.S. Air Forces in Europe, supports four combatant commands by calibrating equipment that requires quantitative measurements, some even as small as the weight difference a signature makes on a coaster.
