Putting together an army that can take on all challenges requires a strong foundation. Your world domination plans start at home. To carry out your strategies, you'll need to generate resources, build stockpiles, and recruit your troops, and all of this requires the real estate to pull it off.

Upgrading a recruitment building to level 2 will enable you to recruit upgraded versions of the respective troop types. You can find a general overview of the available buildings below:

Barracks

An important place to start. A barracks provides housing and training facilities for unarmoured ground troops, so recruitment for infantry and Javelin soldiers happens here.

Vehicle Factory

Once you've gotten yourself established, you'll need to invest in diversifying your army. The vehicle factory contains everything you need to construct and maintain light and heavy tanks, and armoured cars. 

Artillery Factory

Manufacturing explosive shells is delicate work, and so you'll need the dedicated artillery factory to produce support ordnance, such as the artillery unit.

Supplies Industry

Supplies are vital for keeping your troops fed, watered, and in a steady supply of boots. Building this will improve the rate at which you generate supplies.

Alloys Industry

Alloys are important for buildings and vehicles, and represent a mix of all kinds of sturdy, versatile metals and materials. Building this will speed up the collection and smelting of alloys.

Arms Industry

Your war machine needs weapons and ammunition. Build this to improve your supply of war materiel. 

Resource Storage

Producing resources is one thing, but storing them is another. Improving your storage capacity will help you maintain a decent reserve of resources, which ensures a wider range of long-term tactical options. It will also help you weather a longer siege, and help you survive a difficult phase of your war. 

Fortifications

Building fortifications on a province will provide a defensive bonus to any of your troops stationed there.

Capital

The seat of your empire, only one Capital may exist in your nation at any time. This structure provides a morale boost to all nearby provinces.

City Hall

The core of your city. Upgrading the City Hall will open up new construction slots, increase your cash production, and expand your cash reserves.
