Alright. I think I've got it.This link takes you to the Combat Mod planning document that shows the size categories. The first categories of combat classes are the size matters groups. There are three.
The first, Size, considers it's center point to be Medium. Medium has a category rating of 5.
The second, Group volume, has a center point of Battalion. Thus Battalion has a category rating of 5 as well.
The third, Combat Quality, has a center point of Standard. Thus Standard has a category rating of 5.
If you reduce the Combat Quality of a unit to the next level down, Mediocre, the unit would have a -1 category shift overall. If that unit was a Size Medium, Group Battalion and a Mediocre Combat Quality, it's overall SM rank would be 14. All the same but Combat Quality at Superior and you'd have a total of 16 and the unit would be starting off stronger.
In Standard SM all units assume that the core mod strength assigned to that unit is what it would have IF the sum of all combat mod categories (the SM rank) tallies to 15. (an average of 5 for each). IF a unit, like a Royal Guard, has category ratings that add up to a total of 16, then it is a unit that starts a category shift high, as if it began play merged one step or with a quality upgrade perhaps. As a result, the SM version of this unit would enter play much stronger than the core version of the unit.
Both the Tribal Guardian and all the IG's have an SM Rank of 15:I THINK I set up the IG's at a rank shift up one but I'm not sure. Even if I did, it might not be enough if you want a fully merged military unit to have any trouble with it. As a result, this unit would have to be considered a super power unit and we would basically need to use group size and quality to share upgrades each era, making the unit act as strong, at a base that cannot be much manipulated, as perhaps a unit just one shift less than as fully merged as possible. And recall that units can merge as many times as the era count. Thus at Prehistoric, you can merge once. At Ancient, twice. Etc...
- Tribal Guardian: Medium Size, Squad Group, Exceptional Quality => Size 5, Group 3, Qual 7 (Prehistory: 1)
- Early IG, G.d.C., Modern IG: Medium, Company Group, Superior Quality => Size 5, Group 4, Qual 6 (Medieval: 4, Renaissance: 5, Modern: 7)
- Robot IG: Large Size, Solo Group, Elite Quality => Size 6, Group 1, Qual 8 (Nano: 9)
