Just to clarify as I write my response, they've dismounted and are now about to engage the enemy?

I've decided to slightly alter the style, and to make the Brigadier a Generalmajor to fit with our theme. I feel like, for each Sector Division/System Regiment, the rank system and insignia would remain the same butt what they are called is different. Terrans and their culture-aligned sectors would adopt something more Latin-based, Centaurians and their sectors would've had French-based, Orionians and their sectors would be British or American-based. Something kinda irrelevant to us now but definitely worldbuilding.
