Era 2:
Battle Droids- Giving a Droid a gun, and programming them to shoot people. Saves your people, and still gives you an army. Useful, no?
Multi-Terrain Infantry- An invasion army is pitiful if they are stopped by a mere ocean world, or a lava world. Invasions must go on!
Genetics- With knowledge of genetics, your people won't die as easily if you can cure them of genetic diseases, and you can make food yields better, and stuff associated with that.
Galactic Capitalism- Adam Smith's Capitalism, applied to the Galaxy.
Repusolift Vehicles- Vehicles that float can go pretty fast. Then you can transport dudes quickly around.
All Terrain Vehicles- Same with Multi-Terrain Infantry, except with vehicles. And stuff that carries people.
Orbital Shipyards- Need some sort of specialized planet to build your massive navies. So an orbital shipyard is good. 0G is good for building fleets in 0G.
Super Battle Droids- Battle Droids, but super. More armor, better AI. Yay.
Personal Shielding- Apply that starfighter's shields to a person, and you've gotten casualty rates down. Low casualties is good for morale.
Cloning- Clone useful things. Such as an unusually good variety of corn, or Uber troopers.
Trade Unions- Coorporations, unite and form massive monopolies! And umbrella Coorporations and stuff like that.
Tanks- Hovery tanks with improved armor now come back and are useful on the battlefield.
Tactical Fighters- Your X-wings, Y-wings, Droid Star Fighters, TIE Fighters, Tie Bombers, etc.
Frigates- Nice for hit and run missions. Good AA capabilities. Nicely used to shoot down those fighters ripping your capital ships up.
Capital ships- If it's large, and it sails the seas, the Capital ship can destroy it. Also great for planetary bombardment.
Dropships- Stop invading planets 1 man at a time! Now invade with 1000 man dropships.
Destroyer Droids- Shielded Droids with
2 twin blasters of doom... What can be better?
Commandos- Sabotage! Blow up enemies infrastructure. Assassinate. General havoc. Very useful.
Clone troopers- The Uber clone template has been found! Ctrl-C. Ctrl-V. Ctrl-V X a few million.
Battle Walkers- Yeah, those AT-TEs, Spider Walkers, you know. The massive things that walk around and turn people and droids to ash.
Fleet Carriers- Capital ships that carry massive numbers of fighters and bombers. So they are not like 2 to a ship, or stuck on planetary guard duty only. And serves as a nice upgrade for the existing capital ships. To be deathly and have your own fighters!
