Well, I can see the UAV terminal being the downlink, and not a way to operate the bird - THAT takes a full-blown M998 shelter.
If the computer has the sattelite lashup, then it'd work, but could such a thing handle SIPRnet traffic?
A Gator-class vehicle with a 10-K gennie set would have a hellacious noise signature - not sure I'd want that in a tactical scenario, unless I had lots of local security.
