Demo trap

Demo Traps were basic GLA defenses.

The Demo Trap was essentially an IED, with the option for either proximity-based or manual detonation, and hidden from the sight of the majority of enemies. Using Demo Traps, the GLA could considerably slow down enemy advances and give an explosive surprise to over-confident enemy generals who attempted rush tactics. In particular the GLA peppered key routes around its newly-acquired European bases with Demo Traps. Each Demo Trap packed a considerable punch, typically enough to destroy a tank in a single blast. However, once detected by stealth-detection units, such as the Listening Outposts, almost all units could destroy Demo Traps outside of its blast radius (and earn experience in the process). Worker units in Zero Hour can defuse them safely as well, though this risks the owner of the Demo Trap detonating it as they approach the trap.

Demo traps are laid down by GLA Workers for 400 credits. It appears to be a drum filled with either fuel or other explosive material and rigged with a detonator mechanism. They are burried just under the surface, making them stealthed. They have a very large blast radius and strong damage, but are single-shot, disposable weapons. Stealthed ground units that venture too close will set off the proximity fuse, if one is selected. However, the bomb does not actively detect stealthed units. Only effective against surface targets, they are somewhat armored as they can shrug off several shot before detonating.

General Rodall Juhziz, famed for his knowledge of explosives, developed a deadlier Demo Trap - the Advanced Demo Trap.

Dr. Thrax, very well known for his love of Anthrax, used the Toxin Demo Trap, which was less explosive and more expensive, but was filled with Anthrax.
