If you're gonna suggest that the thing speaks for itself, then I have to say it's a really, really bad analogy. A troop of heroic warriors from a fantasy setting, like Grey Wardens, Ash Warriors, the Legion of the Dead, or the Templars are more than a match for any single mage in most circumstances, and no single mage has ever come near the destructive potential of a nuclear weapon.
Fail analogy is fail.
All right, i'll clarify it for you.
Immediate threat - likely the riflemen.
Potential amount of threat though is on the side of bomb.
Can the battalion be frightening and devastating? Sure, and often does. Far too often. But the few examples of what a bomb can do is enough to instill a far greater fear, than any battalion could.
Does a battalion require a belief/objective/training to act as a unified force instead of a whole bunch of individuals with their own short-time objectives? Thats how it usually works.
Does a bomb require special treatment from being used by the wrong hands (aka demons)? Oh yes it does, or the results would be devastating.
Can a single soldier be comparable with a bomb? Never, it requires a mass to achieve comparable destructive results (i am talking about normal commoner, not a heroic a-la Superman characters, like our alter-egos and their band, for the sake of gameover).
Can a battalion wreck more havoc, than a bomb does? Why yes, depending on circumstances, but again it requires a mass and a strong objective to do it.
You can continue with drawing further analogies, but if you are taking it too literally with thinking - no single mage can kill thousands like a bomb does, then you are on too straight and narrow for us to pursue this debate.
