Well then, before the Second Pacific War between the Holy Britannian Empire and the Republic of Japan, Knightmare Frames didn't even got close to exist, the First Generation Knightmare Frame was developed after the Landspinner and Factsphere, they are pretty much useless still, they are used in spearhead attacks, since they are the fatest unit in the game.
Example of 3rd Generation Knightmare Frame: Ganymede
With the build up of Knightmare Frames, Civilian Knightmare Frames shows up, and they do serve as Builders, Search and Rescue, and some other types of Batallions.
After the 3RD Generation, they start to become useful in combat, the research isn't there by mistake, but between the 3rd Generation and the 4th Generation there is the "Slash Harken", they will make mobility way easier in difficulty territories for the Knightmare Frames.
Example of 4rd Generation Knightmare Frame: Glasglow
Glasglows are used by the Knight Police too, they are used to keep the Law in Areas.
The 5th Generation is marked by Anti-Knightmare Designs, they start making Knightmare Frames fit to fight other Knightmare Frames, with that Melee Knightmare Frames with special weapons show up.
Example of 5rd Generation Knightmare Frame: Sutherland
Example of 5Th Generation Melee Knightmare Frame: Gloucester
After that the Energy Shield is made, there are several types of "Energy Shields" two of the best examples are, it will add breakthrough and defense to units that do use the Energy Shields.
Blaze Luminous - Holy Britannian Empire
Radiant Wave Shield - Black Knights
This will liberate the All Puporse Knightmare Frame, i shall keep using Holy Britannian Empire examples only, the All Purpose is a Knightmare that can't be mass produced and its expensive, a single unit can take a year to be made.
All Purpose Knightmare Frame: Lancelot
After that, we will get the Special Weapon, it will add attack to all units.
Well, you can guess what it is right?
Special Weapon: Maser Vibration Sword / Variable Ammunition Repulsion Impact Spitfire / Radiant Wave Surger
It will give us the possibility to research the 6th Generation Melee Knightmare Frame. (No Examples) and the Hadron Cannon.
After that we need the Floater System, no need for explanation for this part, the Floater System will give us a brand new opportunity to make several Airships that are true fortress in the Sky.
Examples:
7th Generation Mass Production Knightmare Frame: Vincent
7th Generation Heavy Artillery Knightmare Frame: Gawain
7th Generation All Purpose Knightmare Frame: Lancelot Conquista
Now the 8th Generation Knightmare Frames are marked by the Custom unit.
Examples:
8Th Generation Mass Production Knightmare Frame: Vincent Ward
8th Generation Mobile Knightmare Frame: Florence
8th Generation Fortress Knightmare Frame: Tristan
8th Generation Melee Knightmare Frame: Percival
8th Generation Heavy Artillery Knightmare Frame: Mordred
What about the 9th Generation?
The 9Th Generation uses Energy Wing, they are extremely fast and so on, but only the All Purpose has the Energy Wing yet. (Wait for 3rd season, i saw Shinkiro with it!)
In compensation, we got the Super Knightmare Frames! The Super Maver Vibration Sword is the Excalibur, the best example is Galahad!
Super Melee Knightmare Frame: Galahad
And the Super Fortress Knightmare Frame that has the ABSOLUTE DEFENSE.
Super Fortress Knightmare Frame: Shinkiro
For the 9th Generation here's the example...
9th Generation All Purpose Knightmare Frame: Lancelot Albion
So here's the suggestion:
Make a Unique Division for the "Unique Types" of Knightmare Frames and put it under the command of a Knight.
The Mass Productino will have stats of its predecessors, for example a 7th Gen. Mass Production Knightmare Frame is going to have the same speed of the 5th Generation Mobile Knightmare Frame, and so on.
