I think our group would be kinda meant to not need that support. I mean, right out of the gate, we have characters that can more or less do what a combat tank could. Our characters are superhumanly strong, fast, and durable. Most of us wield melee weapons, archaic ones, and we can do more with them than a well trained gunman. As we gain more spirits, we'd likely trivialize most standard military armor and vehicles. At the same time, though, we should probably have the authority to direct soldiers we meet and whatnot if necessary, like when trying to get civilians to safety without splitting the party.
