CAPCOM was an agency or title held by a Starfleet officer at Starfleet Command's Fleet Operations Center, Sol Sector.
In January 2155, Starfleet officers R. Simonson, A. Kobayashi, D. Pondella, F. Brookshire, T. Palazzo, R. Cooper, J. Thomas, K. Clark, R. Nomura, and L. Connolly were working in or as CAPCOM. It and the officers' names were listed on directory placards. (ENT: "Demons", directories)
CAPCOM, like many of the other agents and titles on the directories, was a reference to NASA and ISS terminology, in this case, the "Capsule Communicator". It was, as well, the name of a Japanese game company.
