The United States’ national security is a 24/7 endeavor, requiring around-the-clock efforts from thousands of dedicated federal employees and contractors across the country and around the globe.
It’s a larger and more varied workforce than one might expect, and includes under-the-radar, yet undeniably essential, staff like NNSS U1a 2nd shift tunnel miner Ruben Vallejo.
