I've been watching a lot of those grand-scale war-themed movies lately, and they've got me wondering; Would practiced maneuvers/ positions such as the wedge and the phalanx work against the walking dead? If these tactics can be used against the living (who are trained to dodge and evade damage btw), wouldn't they be even more efficient in killing the reckless, berserker hordes of the undead? Also, these soldiers would be armored; I mean, if it can protect from steel, wouldn't it be able to protect from claws and teeth? I know for a fact that zombies would have a hard time biting through: medieval armor, samurai plating, gimp suits, etc.
What do YOU think the pro's and con's would be?
