Supply is a terran gameplay counter limiting the size of a terran force. Every constructed unit takes up supply, and more supply can be generated by constructing supply depots, up to a maximum value of 200. New units can be produced so long as the cumulative supply of all active units does not exceed the number of available supply.
In strategy discussions, supply levels may be denoted as x/y, where x is the supply used, and y is the total available supply. Unit costs may be denoted as x/y/z, where x is the cost in minerals, y is the cost in gas, and z is how much supply is used.
