Yellow: There is insufficient supply for the units in this province, but there is still enough to provide a reasonable partial level of supply.Purple: there is a small amount, or no available supply, but there are no units suffering from the effects of low supply in this province.Dark blue: there is a small amount of available supply.Bright (light) blue: there is a large amount of available supply.These change in gradients to elegantly display the supply situation at a province level in a way that is digestible for hundreds of provinces at once. The supply mapmode shades each province by its supply situation. This is accessed (using default settings) with the “F4” key, or selecting the mapmode from the icon in the bottom-right corner of the screen. Supply is shown in the game primarily via the supply mapmode. The two crates in the map mode selection area in the bottom-right of the screen indicate the supply map mode.

Once the total supply required is more than that available, the units affected will experience penalties (more on that below). In effect, state supply is applied first, hub supply applied second, and air supply accessed last.Īs long as the total amount of supplies required by units in the province is less than that supplied, units will be fully supplied. One thing to bear in mind is that units with available hub supply will still draw state supply, even if the hub supply is sufficient for that units’ needs.State supply is a fixed level of supply for each state, that is available to all units in that state (for a contested state, state supply is split between the contesting nations).

Aerial supply is provided by transport aircraft on a dedicated mission and is available in an air zone.

Hub supply is provided by the network of supply hubs, ports, railroads and convoy routes that distribute supply from your capital to your forces at the front. The level of supply available in a province is made up of three different sources – “Hub Supply”, "Aerial Supply" and “State Supply”. Each land unit also has an internal supply situation, that is separate from, but related to, the level of supply in a province. Supplies are not produced, but rather the level of supply in a province represents a “support capacity” (it could be thought of as a soft stacking limit). If you spot a mistake, please help with fixing it.
