Home Base
The Home Base is unique and unconquerable. If it is destroyed, you receive a new one at the starting level. It is the core of your setup. Temporary enhancement of the base defense armor (symbolized by the flag) is not possible at the Home Base. The Home Base can be recognized by the green "Home Base" writing on the wall, and on the minimap it is a circle with an H in the center. The Home Base can only build ground vehicles.
Tank Base
The Tank Base produces only ground vehicles and is the most common type of base on the map. When a map restarts, many Tank Bases are available. Heavier tanks can be built in the Tank Base than in the Home Base.
Helicopter Base
The Helicopter Base produces both helicopters and ground vehicles. There are also versions with a shipyard, allowing the construction of boats and ships, or with a train station, allowing the construction of armored trains. Thanks to its large hangar, the Helicopter Base can build ground vehicles that are not buildable in a normal Tank Base.
Air Base
The Air Base produces both aircraft and ground vehicles. Vehicles can be built in the Air Base that are not possible in normal Tank Bases. Air Bases are very rare and therefore hotly contested.
Harbor Base
The Harbor Base enables the construction of boats and ships that can move within the river; you can build them by hovering the mouse over the shipyard located in the water. The Harbor Base can also build tanks like the Tank Base. The Harbor Base is also rare, but sometimes comes with a helicopter hangar, then it is possible to build tanks, boats, ships, and helicopters.
Train Station Base
The Train Station Base builds armored trains in addition to ground vehicles like a normal Tank Base. It is sometimes, but rarely, also available with a helicopter hangar, then it can build ground vehicles, armored trains, and helicopters. Armored trains can only move on the rails, and you can build them by hovering the mouse over the train station, which opens the build menu with the armored trains.
