U.S. Airmen from the 137th Special Operations Logistics Readiness Squadron (SOLRS) at Will Rogers Air National Guard Base, Oklahoma, tour a 1st SOLRS bulk fuel storage tank during annual training conducted at Hurlburt Field, Florida, July 27, 2021. It is not common to see the inside of a bulk fuel storage tank within the fuels career field as the tanks are only emptied of jet fuel for inspections once every 10 years.
