So this is what I am working on lately. So red alert 1, yet so fitting to use in a Sci-Fi Millitary game that will include Furry Islanders.

The Workstation is actually a mix of Red Alert 1 Construction Yards and Ore Refineries in design. Not Quite what should be a main headquarters in a base, but it is capable of assembling the major working unit, which we will just call Multi-Functional Work Vehicle... Needs a name change.
A Gulag will provide Supply for units to be produced, just like a Terran Supply Depot, Pylon, and Overlord in Starcraft. Lorewise, such a structure is where they assemble basic stuff for millitary personnel to use.
Gas Refinery... Well, built upon, like, a Vespene Geyser, it will provide an active Gas supply for the worker units to pick up.
Barracks remains the infantry training facility, Providing commanders with Conscripts, Tesla Troopers, Combat Engineers (Aka Medics for vehicles) and Saboteurs (Soviet-ish commando).
A Weapons Plant will give a commander Access to upgrades for Ground and Air Weaponry, adding an attack bonus each level. This will have an Armor counterpart, let's name it Armor Plant, adding upgrades for ground and air unit armor.

In order to use more advanced units, some extra buildings will need to be built. Radar Domes and Localized War Factories will do their part unlocking the more powerful Apocalypse Tank, the Huge Kirow Airship, and the Saboteur.
