I would honestly not be opposed to swapping Trauma's unit for alpha arc. With the current system, everyone joins rancor to be ARC, nobody has the desire to go down the ARF path. If we replace them, it'll ensure ARC is the path they go, with Alpha being the better part of the ARCs in rancor.
My second opinion was to indeed try to get Kal known as the "Advisor." As was his official title in the G.A.R. I like your Idea. @Square@Freck I'd be fine with either of these, should my thing here get accepted.
Imo all you saying Kal is wrong for this spot is kinda silly. After all. He did work with Delta. They followed him in combat. " They took part in the shut down of a Separatist terror cell operating on Coruscant. The squad would be tasked with locating the Kaminoan defector Ko Sai, though their search would turn up nothing but the scientist's severed head."
Sev loved Kal.
"Sev also felt a sense of jealously toward the commandos who had been trained by Kal Skirata, who treated his trainees as though they were his sons. "
This makes perfect sense to me to make Kal SOBDE Reg.He pretty much is. imo.
I would like to point this out in Lore kal Skirata was never the leader of the Null class ARC troopers it was ordo skirata all he did was adopt them and train them I honestly feel that Kal moving up to reg would be better cause kal was always a overseer of the squads as well as walon vau. I feel like you guys should read up on your lore. Also it wouldn't at all be a bad idea ordo would just become the leader of it and kal would just move into the reg position and not have to run just null.
