The battle prolonged for a couple of turns, yet it was clear that since turn 2 that the upper hand was on Leon and his companions. The tide of the battle itself might be turned otherwise if Leon should fight alone, as he realized for sure, that even though Rugal or Galor was a strong unit, having only one at the time to fight would put him in a disadvantaged situation.
As he gave the command to Galor for the many times and it attacked an enemy unit, killing them, Leon was reminded of Ahli who was only supported by one unit as well, and not to mention was weaker than Rugal, but able to fight against a bunch of enemies and surviving it. It really showed the difference of not just raw power of the system they had, but also the skill of its user as well.
