Age of Empires Series Wiki

Supplies is a technology in Age of Empires II: Definitive Edition that can be researched at the Barracks once the Feudal Age is reached. Once researched, it decreases the food cost of the Militia line units by 15.

With the introduction of Supplies, Tracking was removed from the Barracks, and Supplies took its place as the Feudal Age Barracks technology.

Since Supplies costs 75 food, this technology starts to pay out food-wise if more than 5 Militia line units are trained after researching it.

The Gurjaras' Militia line is the cheapest in the game due to their Castle Age unique technology Kshatriyas, which reduces the food cost by 25%, and their access to Supplies, ending with a cost of 30 food, 20 gold (for a total of 50 resources). However, they lack Gambesons, Squires, Champion, and Blast Furnace.

Despite lacking access to Supplies, the Goths have the second cheapest Militia line in the game due to their civilization bonus that lowers the cost of infantry by 20%/25%/30%/35% in the Dark/Feudal/Castle/Imperial Age, so it ends up with a cost of 39 food, 13 gold (for a total of 52 resources).

The Incas also lack Supplies, but compensate for it with their civilization bonus that lowers the food cost of all military units by 10%/15%/20%/25% in the Dark/Feudal/Castle/Imperial Age, so it ends up same as Supplies for the Militia line in the Imperial Age.

  • Portuguese: With update 73855, all technologies are researched 25% faster as a team bonus.
  • With update 81058, research time reduced to 20 seconds. Incas lose Supplies. Bengalis gain Supplies.


  • Despite being introduced in the Definitive Edition, only one of the new civilizations introduced, the Bulgarians, have access to it.
  • If a Gurjara player researches both Supplies and Kshatriyas (which lowers military units food cost by 25%), their Militia line will cost 30 food, 20 gold regardless of the order of research. This happens due to a trigger that sets the food cost at 30 if both technologies are researched.
  • If the cheat code "above and beyond" is used, and the player has access to Supplies, after researching it more than four times, the food cost of the Militia will be negative. That is because Supplies reduces food cost by 15 per research, instead of -25% food.
  • The icon of the technology looks nearly identical to the icon of a crate of food in Age of Empires III.
