[Suggestion for some "eye-catching" units in CMBN]

Making the table "crew served" and have it function like a gun is actually brilliant. You'd need to "limber" it to pack it up for transport, you'd "unlimber" it when setting it up, and preferably you'd transport it by a loading it unto a truck or a jeep/K-wagen. Carrying it would be slow. And the HQ team, i.e. the "crew", could "bail out" and ditch the table in an emergancy, just as you say.
