The Combine use a large array of science fiction technology. They have access to teleportation technology, which takes them from their dimension to Earth. However, their teleporter technology is restrictive in comparison to that developed by Eli Vance, Isaac Kleiner and Judith Mossman in that it cannot be used to teleport to other locations on Earth without significant modification.Throughout the games, various futuristic computer consoles, doors, power sources and weapon emplacements are encountered. In addition, the Combine employ the use of small airborne robots, scanners, to observe the citizens of Earth. The city variant merely moves about the streets, monitors individuals, and takes photographs, while the combat equivalent is capable of dropping mines into an area.Civil Protection makes use of smaller airborne robots called manhacks, which fly using razor-sharp rotating blades with which they attack their targets to cause incision injuries. These are often deployed in closed-in areas. The Combine also use two types of land mines; hopper mines throw themselves into the air and detonate when an enemy is detected nearby, while the spherical rollermines roll towards vehicles or other enemies, attache themselves and delivers damaging electrical attacks.Combine technology is also used to transform humans into Overwatch soldiers or stalkers, deformed and mutilated humans with no memory of their past selves who act as slaves and maintenance workers in Combine facilities. Transformation into a Stalker is considered among the Combine's worst punishments for dissidents.Militarily, the Combine make use of both synthetic machines powered by organic components and traditional mechanical machines such as armored personnel carriers and attack helicopters.The most prominent of the synthetic machines are the insect-like gunships; and Striders, 50-foot-tall (15 m) armored creatures that walk upon three legs, which are armed with a high powered warpspace cannon and a head-mounted pulse turret.In Episode Two, a smaller equivalent to the Strider, the Hunter, is introduced. These 2.5 m (8 ft) tall, tripodal assault machines fire explosive flechettes at targets and are small enough to maneuver indoors. Other synths are seen near the end of the Half-Life 2, although their roles are not elaborated on. Sentry turrets are also used by the Combine.The Combine also use headcrabs as a biological weapon against dissidents, firing artillery shells loaded with the creatures into areas and allowing them to infest the vicinity.
