A human wave attack, also known as a human sea attack,[1] is an offensive infantry tactic in which an attacker conducts an unprotected frontal assault with densely concentrated infantry formations against the enemy line, intended to overrun and overwhelm the defenders by engaging in melee combat. The name refers to the concept of a coordinated mass of soldiers falling upon an enemy force and sweeping them away with sheer weight and momentum, like an ocean wave breaking on a beach.
