Instead of leading the undead on for miles, bait will draw them to a fixed position. This position could be constructed of debris, hastily erected barbed wire, wrecked cars, or your own vehicles. From the fixed position, your team will stand its ground, killing the zombies before they can overrun the barricade. In this instance, incendiary devices are ideal. A flamethrower (only in this case) would utterly destroy their ranks. If incineration is not an option, simple marksmanship will accomplish the same task. Make sure your distances are measured and your rounds are expended wisely. Use the barricade tactic in urban areas or those that provide great visibility. Specifically exclude jungles, swamps, or thick forests.
