In Starcraft, the Bulldog Build involves one shuttle, and two reavers. By contrast, the Mandog Build opts for two shuttles and no reaver. This build forgoes the destructive power of reavers in favour of the surprise effect of unloading up to 8 zealots right on top of your opponents key units, like siege tanks.
"Two shuttles, no reaver! That is called the Mandog Build from now on, because all you rely on is flying men. A flying Bruce Lee drop, right in front of you, like a flying wall of fists. All of a sudden, you are a siege tank standing there and BOOM! Fifteen fists appear in your face."
