File:Q4.png In Quake 4, the Guard, also known as the Strogg Marine, is a Strogg guard consisting of a naked Stroggified human with mechanical legs and a small arm-cannon for a right arm. Although very weak, they are quite numerous, often attacking in groups of several at once; they are the most commonly encountered enemies you face throughout the game, and are seen in almost every level of the game. However, later in the game they are replaced by the more advanced Tactical Strogg as the major cannon fodder enemy you face.
