Game Building

The Bunker holds a key role in Terran Defense. The structure is unable to attack, on its own, and has to be loaded with infantry units, thus offering them a safer spot from which to attack. When a Bunker is destroyed, the units inside it emerge unharmed and will continue to attack enemy units.

StarCraft 2 Building

In StarCraft II, the Bunker can hold up to four slots of infantry, or more through upgrades. Units inside it will be granted a +1 to attack range bonus.

Abilities

The Bunker can use the following abilities.

• Load. Loads infantry into Bunker.
• Unload All. Unloads all units.
• Salvage. Salvages the structure, removing it and returning 100% of its resource value. Takes 5 seconds and cannot be cancelled once triggered.

Upgrades

The Bunker will benefit from the following upgrades, which can be researched at the Engineering Bay.

• Neosteel Frame. Increases cargo space of bunkers by 2.
• Building Armor. Increases Terran structures armor by 2.
• Shrike Turret (Single Player only)

StarCraft 1 Building

In a similar fashion to the Protoss Photon Cannon, the Bunker is immobile and is designed to protect the immediate around around it.

The Bunker itself does not attack, instead it relies on the player loading it with infantry units such as the Marine, Firebat and/or Ghost. Similar to StarCraft II, the units inside are not hurt when the Bunker is destroyed.

Abilities

• None

Production

The Bunker produces no units in StarCraft I.

Upgrades

The Bunker receives no upgrades in StarCraft I.

Defensive Bunker

The Bunker is first and foremost a defensive structure designed to protect the Terran base from attacks. They can be placed sparingly around the base to prevent hit-and-run tactics from Reapers (in StarCraft II), drop attacks with Dropships and/or Mutalisk harassment, or built at the front door to provide support against an enemy attack. A Bunker at an expansion can also provide the protection it needs until reinforcements arrives.

A common strategy is to "wall-in" or "turtle", whereby the Terran player builds several Supply Depots at a choke point or ramp to prevent the enemy from entering the base. One or two Bunkers can than be placed behind the wall to provide covering fire.

In StarCraft I it was counter productive to simply use Supply Depots to block the entrance as there would be no exit point for an army. In this case, one or two of the Depots would be replaced by a Barracks or Engineering Bay that would uplift to provide an exit.

StarCraft II has given the Supply Depots the ability to lower themselves, thus allowing units to walk over them. The Planetary Fortress upgrade for the Command Center is an excellent additional structure and works well when combined with the Bunker.

Offensive Bunker

The offensive Bunker can be an effective early game strategy that relies on catching the enemy by surprise. Similar to the Protoss offensive Photon Cannon push, the premise is to send an SCV across with three or four Marines as an initial attack group and begin setting up outside their base - preferably outside their field of vision.

Once the first bunker is complete and fully loaded, the player can then "leap frog" additional bunkers closer and closer to the enemy's base. Each subsequent bunker will be protected by the building behind it. If the enemy decides to attack the bunker fortification, the SCV can repair the structure while the infantry inside can return fire. In this case, having more than one SCV will result in a faster repair and an almost invincible bunker.

Sunken Colonies and Photon Cannons have a larger attack range than the Bunker and can be an effective means of halting a push, as too is the Zerg creep which the SCV can not build on. Zealots are also effective at rushing a bunker due to their high HP and shields.

A Bunker push appears to be more effective in StarCraft II due to the two additional upgrades available from the Engineering Bay. Neosteel Frames enhances the carrying capacity of a bunker from 4 to 6, allowing more infantry to be placed inside and therefore more damage to be done to those who choose to attack it. Building Armor is the second upgrade, which increases the Bunker's (and all Terran buildings) armor rating by +2 for a total of 3. The Bunker itself also provides a +1 range bonus, and old bunkers at the back of the line can be Salvaged for a full refund.

If the enemy is successful in halting the Bunker push, the player can continue their tech until Siege Tanks which will provide the range and additional support needed to break a stalemate.

The overall goal is to distract the enemy enough that they choose to focus on destroying the Bunkers, usually wasting resources or changing their strategy to compensate for the new turn of events.

The offensive bunker is rarely seen in pro-games in StarCraft I and it is unknown how widespread this will be used in StarCraft II.
