Shepherds, also known as Peace Makers, are humanoid DeeBees and are the standard DeeBee encountered on the battlefield. They are armed with the Enforcer Submachine Gun, providing light fire but often in larger numbers.
Like other DeeBees, the Shepherds were not initially built for intense combat, but for security and more dangerous labor jobs to keep the remaining human population safe, hence their common recommendation of "social" behavior in their dialogue. These non-lethal security units are known as Peace Keepers and are equipped with Shock Enforcers and an electrically charged whip to suppress any security threats.
The Shepherd DeeBee is a playable multiplayer character for the Swarm in Gears of War 4. Excluding its default skin, the Shepherd has eight unlockable character skins: Color Blast, Construction, Desert Camo, Ninja, Red Tiger Camo, Red Wave, Shadow, and Vintage. Its Construction skin is only available in the DB Industries Gear Pack.
