Step-by-step explanation:
The office primarily responsible for the PRIME BEEF program is the Civil Engineer Squadron or the CES.
The PRIME BEEF program stands for **Prime Base Engineer Emergency Force** and it provides support for rapid response and recovery to natural disasters or emergencies that impact military installations. The program is managed by the Civil Engineer Squadron, which falls under the responsibility of the U.S. Air Force.
