I am a veteran, and shipping containers like these are used for all sorts of stuff in the military. They're used for workspace on every base in the US and overseas, set up for living quarters and restrooms/showers overseas, used as medical/dental offices overseas and some bases in the US, used for storage and shipping, and all sorts of other stuff. Being that that are several military bases in and around San Diego where TPTW is located, i could definitely see them landing some military contracts.
