Later, the term "human wave attack" was often misused to describe the Chinese short attack — a combination of infiltration and shock tactics employed by the People's Volunteer Army (PVA) during the Korean War. According to some accounts, Marshal Peng Dehuai—the overall commander of the PVA forces in Korea—is said to have invented this tactic. A typical Chinese short attack was carried out at night by small fireteams on a narrow front against the weakest point in enemy defenses. The PVA assault team would crawl undetected within grenade range, then launch surprise attacks against the defenders in order to breach the defenses by relying on maximum shock and confusion.
