I've been thinking about what other space or land units that the CSA can use for now until they get an upgrade in later updates. I'll list ten units they can have/can get by going to other planet's watch i find okay but they can use if say you build a fleet shipyard like the Republic and Empire can use.

10. Acclamator 1's (I know you can get the 2's at Kuat but maybe just have one as Carriers for the CSA to use)
9. 5a Juggernaut (or 6's or both)
8. TX 130's (both types)
7. Providence Class Carrier/Destroyer/Dreadnought (But only get them at Mon Cal and other CIS Shipyards)
6. HAG, artillery vehicle
5. Espowalker 91/101's (thou i know they will get them in a Future update)
4. AAT
3. Munificent Class Frigate
2. AT-TE (Or the AT-HE)
1. MALEVOLENCE Class Dreadnought.
