== Supply Depots ==
Supply depots (aka "supply sources" or "supply centers"), are a physical location on the map where all excess supply in a landmass region will try to travel to each day 1 province per day. The national supply tooltip information is a direct extraction of all the values of the capital province in supply map mode. If supply production is currently on in the production tab then a tooltip on that slider will show how much supply units will be produced for the next day. That value on the next day at 000 will deploy divided amongst all IC provinces
in your land that can draw a supply line to the capital stockpile. If its overseas then it will only deploy overseas if a supply convoy is setup to the landmass. Effective IC is the modified IC value of a province. Overseas, war damage, and occupation policies effect the IC values of provinces therefore core unthreatened IC provinces will always recieve more supply each day from production than overseas frontline IC provinces.
# The overseas supply source for any territory not connected to a nation's main land is a port.
The tooltips for the national stockpile on the top of the screen are: Into network= How much supply is transferring from your capital land province into adjacent provinces
Convoyed out= How much supply is being sent out in convoys each day(supply does not travel from the capital to a port to ship out through a convoy, supply will magically just ship out with no effect on the supply map mode.
Returned to stockpile= Excess supply that is transferred into the capital province that day from adjacent provinces or a convoy from a landmass that is empty of units but has supply present in it.
Traded away= supplies you are selling to a nation or supplies distributed to an ally to cover costs of your units operating in their supply networks
Traded for= Supply coming in from nations you bought supply from.
Supply used by units locally in the capital province.
Produced= the value from the previous day in the production slider tooltip for supply production.
Apart from supply sources, any province that has received more supplies than the units in that province used will temporarily store these supplies. Thus, these supplies can be captured if the province is captured. After a short period of time, any provinces with surplus supplies (other than a supply depot) will send them back to a supply depot along the supply network. There is no throughput cap on supplies heading back to the center, and no supply tax.
