So I had this goofy idea recently thanks to all the recognition guides for the IlClan era; I felt kinda miffed about the RoTS forces, because while I was never very attached to them, I really didn't like how absolutely apeshit they function and play. RoTS basically, have no consistency or "theme" like other factions do, to the point where they feel almost Schizophrenic- I really didn't like that flavor, and I thought "Well, what if I made them more effective that would make the Wolf takeover more impressive?"
So like the other houses, I checked what they can make and decided to make some fun mixtech forces that give the RoTS some actual cohesion. I settled on what was made out of Eris for the Jackrabbit and Malice -YZ as well as Devil's Rock for the Ares; I also took note of the number of Drone 'mechs the RoTS was using and considered, that perhaps the Republic doesn't have the mechwarriors needed, or is pulling modern military concepts of quality over quantity? Thus, a few ideas came about- one, all the 'mechs have to be refits of existing designs that only have a small spread of clantech available from those sources. Two, pilot surrvivability has to be top-tier, so they make HEAVY use of anything that can protect the 'mech and keep it from being hit. Three, standard C3 is used, because everything has heavy electronics and those requirements mean less payload space for guns. Finally, Void-Signature would get is it's own spread of units as a "Interesting, but actually bad idea" sort of fluff decision.
This left these techs produced:
