One of the things you see in some Sci-Fi settings is the idea of modular buildings able to be rapidly set up to offer facilities to a command sent somewhere new. Starship troopers, Space Above & Beyond, Star Wars and even Star Trek all had rapid set up (or drop off as the case maybe) buildings ground forces- or support for aero forces on the ground- would use for barracks, rec, tac/strat, storage and repair.
What sort of things do you think should be available to Houses & mercs for such rapid deployments? What might be the most common/popular?
If you know links to real systems, it would also be cool to see.
I think some of the top would be-
Vehicle Repair Bay
Something like-
or
Stack them 3 high, IMO using I-beams as girders for stability, and you could have a mech repair bay, using the containers to mount or open doors for gantry walks. Inside each container would be the tools and equipment to repair vehicles or armor. If the frame of the structure uses I-beams then you should be able to easily work of a overhead winch/crane . . . or you use vehicle versions to get into action faster.
For barracks-
If you do not want them dug in, then below is a option- they even have AC/heat judging by the picture. For something more protected you can put up sandbags or their 31st century equivalent. Or if you have quick working engineers, you can dig a trench to put them in.
