still Ι do not understand why this example is right

Q:
If assigning damage to a figure upgrade that is in the
middle tray in the front rank of a unit would cause that
unit to be split into two separate groups of trays, must that
damage be assigned to another eligible figure?
A:
Yes.
Example: A Spearmen unit equipped with Front Line Rune
Golem has only its front rank remaining. The Rune Golem
figure is in the middle tray of the unit’s front rank. That figure
upgrade cannot be assigned damage that would cause the unit
to be split into two groups.

If a unit is made up of a single rank, that rank is both the front and back rank.

When you are down to a single rank, you are correct that it is both the front and the back, so you can assign damage to any figure upgrade without needing accuracy results UNLESS two conditions are met: 1) that figure upgrade is in the middle tray, and 2) removing that figure upgrade would cause the unit to be split or in other words, that figure upgrade is the last figure in the middle tray. In this case, you cannot assign damage to that figure upgrade until one of the side trays is removed.

Let me just say that you have singled out what is, in my opinion, probably the worst "gamey" rules interaction in the entirety of Runewars.

I don't like it, myself. I gather most people don't like it. I don't even think the designers like it. It seems to exist to enhance ease of play at the cost of balance and good sense.

The fact that a single rank unit is both front/back rank is immaterial. Legally speaking, you SHOULD be able to kill the single tray model in the middle of the unit (it is a valid targeting choice) but, because that would force you to split a unit in two, this would necessitate a whole other rule telling us how to then reform the two disparate portions of the unit into one. Does the right half shift left? Does the left half shift right? How does it work?

It would be a point of confusion, and something that was probably argued about and misunderstood. It is easier just to say "you can't split units" and move on, even if this isn't the most satisfying rule, and prone to (mild) abuse.

Work it like removing figures. Slide one side over to fill in the space that opened in the middle. The attacker gets to choose which side slides over, and has the option of closing in, if applicable.

Unfortunately, that's not the rule we have.

Also: Hey Xelto, good to see ya

I agree that this would have been the most sensible solution.
