I have a lot of experience in scripting in KaM. I've found that it i much easier to have specific players for special attacks (such as attacks at the start of the mission). This eliminates any complications in having merged players. In this case, since the axe-fighters that attack your tower belong to a different player than the rest of the enemy in your base, there is no chance of the axe-fighters leaving the tower alone to run to their allies aid, because they are completely oblivious to everything else going on around them.
As you are no doubt aware, KaM uses defensive positions to organize AI soldiers. Another benefit of separating players is to make managing these defensive positions easier. I imagine that this could have also contributed to the separation of players.
If you don't mind me asking, why is there a problem with there being three players? Is this just a curiosity? Or is this part of your work with the new AI that you are developing? Or am I completely wrong altogether
