I was obviously talking about common soldiers, the ones that most of us are common with in the past two games. Besides, I wouldn't call Ravanna a soldier. She's a warrior.
The main difference between warriors and soldiers is that warriors are just to combat (hand-to-hand) while soldiers are called upon for many different tasks which aid in warefare. For instance, the Roman army had soldiers for building bridges with their great engineering, changing the terrain and setting up war engines to prepare for battle, as well as fighting. The Roman Gladiators were warriors, only fighting hand to hand, not a part of the greater picture of war (in fact, they were just an extracted piece of war: the hand-to-hand combat part).
I don't think Ravanna was a part of what would be a body of soldiers. Soldiers tend to be like ants, working on projects together, and are never on top. Ravanna, however, is very close to Xena; she works as a very high-ranking official. I doubt she ever worked in a body of soldiers (basically minions doing the bidding of others), and she is more than prominent enough to simply be the directress of soldiers, not one of many of her equals working for a greater cause.
Ravanna only fights and leads others. She is litterally a Warrior Princess™.
