Well I included these from my old Star Trek RPG back in the 80s:
Starfleet Unit Citation - for outstanding service as a unit, additional awards add sunbursts (1 award) or clusters (5 awards).
Starfleet Combat Star - for participation in a combat action, additional awards add palms (1 award) or clusters (5 awards).
Starfleet Combat Command Star - for command in a combat action, additional awards add palms (1 award) or clusters (5 awards).
Star of Sirius - for combat action during the Earth-Romulan War, with Gold Comet for a combat command.
Blantar Award of Valor - for combat action during the Federation-Klingon War, with Silver Asteriod for a combat command.
Axanar Medal - for combat action during the Four Years War, with Nova for combat command, with Lightning Bolt for Combat Flag Officers.
They all worked with the timeline I was using at the time so they don't really fit with the Okudachron, but a thing is what it is. They could still be adapted.
BTW those are but 6 out of the 33 Commendations and Awards of Valor that I was using at the time.
