A simple idea:
As your tier increases, you go from a Recruit, up to an Admiral
Rather than remain a recruit all the way
It can increase every 10 tiers:
Tier 1-9: Recruit
Tier 10-19: Private First Class
Tier 20-29: Corporal
Tier 30-39: Sergeant
Tier 40-49: Warrant Officer
Tier 50-59: Lieutenant
Tier 60-69: Captain
Tier 70-79: Major
Tier 80-89: Colonel
Tier 90-98: (Brigadier/Major/Lieutenant) General
Tier 99: Admiral (I know it’s the same as a General, but hey)
The Developer: Grand Admiral
You can modify it as you see fit. These Rank names are just placeholders, but they can work, too.
Optional: Perhaps your ship could have an Insignia that changes too? (It could be on the right side of your name, since the CHL is on the left)
There could also be a Rank Selector if you’ve already unlocked a few ranks. You can be a Rank 99 Private First Class if you for some reason want to.
