Yes, IF there has to be a nuclear weapon it should be something like the DC. But since that was a crew operated recoilless rifle the uses in game would be limited. More like a quest-related one shot experience than a portable nuke. Perhaps hearing rumours about it, then searching for and repairing it, then looking for a shell and hauling that to the gun and finally firing it at some SM or Talon camp.
