This technology is unavailable until industry is researched enough. Infrastructure may only be built once the appropriate technology is researched. Many poorer or more rural areas of europe will start with less than complete infrastructure but still usually have at least 8/10 infrastructure. The provinces that start with lower infrustructure are places like those in Africa or certain parts of the Soviet Union. Most provinces start the game with a high infrastructure score. Infrastructure is used to transport supplies and units around the map. They can also nicely complement fighter support as well as AA units (not to be confused with provincial AA Guns). Because of how fast and cheap they are to build, however, one can take a province from 0 to 10 AA guns in about a year and a half. When level bombers bomb a province, a few AA Guns are usually not enough to fight them off and the AA Guns will soon be damaged and rendered useless until they repair. Defending at a river is often a better choice than taking the time to build Land Forts, meaning building Land forts across rivers will be the best choice.ĪA Guns are very quick to be built but are not very effective in small numbers. This is a very significant debuff, but it takes years to take a tile from 0 forts to 10 forts and is very expensive in IC. A tile that has a full 10, undamaged, forts gives a -90% modifier on any army that is attacking this tile. This IC is used to build things in the production menu.Ī coastal fort gives a combat bonus to a land unit stationed in that province when a enemy unit try an invasion from the sea to that province.Įach level of land fort increases the defensive bonus of that tile by a small amount.

Also allows more resources/supplies/fuel to be shipped through that province.Įach level gives an unmodified IC of 1. A higher Naval Base score improves repair/organization regain rates. A higher Air Base score improves repair/organization regain rates as well as allows more supply to be used by the base, which means more planes can be used in that province.Īllow for the docking of ships. Air Bases allow for planes to land there.
