StarCraft: Brood War/Protoss Mission 5: The Battle of Braxis

You start with a small force of 3 Scouts, 2 Shuttles, 4 Zealots, 2 Dragoons, Artanis and 3 Observers. You are at Level 2 with all your upgrades. Note that you are limited to what you are given in this mission, but you get reinforcements as you destroy each Power Generator. Your first target is obvious; the one closest to you on the map. Use your observers strategically throughout this mission; take out any Missile Turrets you have to, and rely on your ground force. As soon as you destroy a Power Generator, all Missile Turrets in the area will no longer attack you, but rather serve as your additional detectors.

Destroying the first Power Generator will give you 3 Shuttles, 2 Dragoons, 4 Zealots and 4 Dark Templar.

Destroying a second Power Generator will give you 2 Shuttles, 2 Dragoons, and 4 Dark Templar.

Destroying a third Power Generator will give you 2 Observers, 2 Reavers, 3 Shuttles, 4 High Templar, 2 Dragoons.

Destroying a fourth Power Generator will give you an enormous force of 1 Arbiter, 4 Corsairs, 6 Scouts, 8 Zealots, 2 Shuttles.
