Destructible Rocks are neutral structures placed on maps usually to initially block paths or expansion areas. The rocks can be attacked by any unit that can attack ground units and will crumble and give way once their health reaches zero. Like all buildings, Destructible Rocks have the Structure attribute, meaning that they will take additional damage from Nukes and Banelings.

Destructible Debris is a mere visual variation commonly used on maps using the Urban and Space Platform tilesets in place of Destructible Rocks.

Notable Uses

• Blocking backdoor entrances of main bases or key expansions, leaving them a lot more vulnerable once the rocks are destroyed.

Notable occurrences: Blistering Sands, Kulas Ravine, Desert Oasis, Ohana.

• At (usually gold) expansions blocking the spot a Command Center, Hatchery or Nexus would have to be placed for optimal resource gathering.

Notable occurrences: Blistering Sands, Delta Quadrant, Lost Temple, Xel'Naga Caverns.

• Blocking access to expansion areas which are effectively islands until the rocks are destroyed.

Notable occurrences: Kulas Ravine, Scrap Station, Steppes of War, Entombed Valley.

• Blocking shortcut paths between two main bases.

Notable occurrences: Incineration Zone, Kulas Ravine, Scrap Station.

• (Wings of Liberty only): Allowing Void Rays to easily build up their charge for a more powerful attack on a nearby base. Usually a side effect, not a direct goal in map design.

Destruction Time Statistics

Below you can find a breakdown of how long it will take a single unit of a certain kind to take down one pile of Destructible Rocks. This list is useful, for instance, if you want to figure out how many Marines you need to send to kill a set of rocks if you need the area to be cleared in a certain foreseeable amount of time. All times assume no upgrades. Note how the high armor value of destructible debris means that units with low damage per attack but rapid/multiple hit attacks take a great deal longer than those with higher base damage.

Patch Changes

Patch 2.0.7
An attack command is now required in order to attack Destructible Rocks, which are no longer automatically attacked by units when right-clicked.

Patch 5.0.15
Fixed an issue where the model for Zerg 6x6 rocks was set to be too large for its footprint, and projectiles would not produce flesh squibs.
