The Case of the Missing Army: She-Ra and the Princesses of Power, and the Battle of Bright Moon

For a show about a rebellion against an evil horde, She-Ra and the Princesses of Power doesn’t contain very many battles. Or, scratch that: She-Ra and the Princesses of Power contains many battles, but only one side ever actually fields an army.

How can a rebellion not have an army? Well, they do. One army is mentioned but never seen, but the other army, while slightly more visible, never fights in any battles—even when their entire rebellion is at stake. Why might we never see the forces of good take the field in She-Ra and the Princesses of Power, then?
