According to U.S. Army analyst Edward C. O'Dowd, the technical definition of a human wave attack tactic is a frontal assault by densely concentrated infantry formations against an enemy line, without any attempts to shield or to mask the attacker's movement. The goal of a human wave attack is to maneuver as many men as possible into close range, hoping that the shock from a large mass of attackers engaged in melee combat would force the enemy to disintegrate or fall back.
