Supply block

From Liquipedia StarCraft Brood War Wiki

Supply block (or supply stuck) is when a player's unit production is halted until greater unit capacity (or "food") is prepared. This typically delays a build order and can ruin the window of opportunity. Experienced players avoid supply block by continuously building pylons/overlords/supply depots before they reach unit capacity. In the later stages of a game one player may gain an advantage over another by destroying many capacity-providing buildings/units.

StarCraft reminds a player with audio cues.

  • Protoss: "You must construct additional pylons."
  • Terran: "Additional supply depots required."
  • Zerg: "Spawn more overlords."
