Shock tactics, shock tactic or Shock attack is the name of an offensive maneuver in battle in which the attacking forces engage into close combat with extreme action and massive force. The shock tactic is a fully committed attack designed as a sledgehammer blow against the enemy and aimed to break their formations, shatter their morale and eventually rout their soldiers.
Shock tactics were usually performed by heavy cavalry, but was sometimes achieved by heavy infantry. The most famous shock tactic is the medieval cavalry charge. This shock attack was conducted by heavily armoured cavalry armed with lances, usually couched, galloping at full speed against enemy formation.
At World War II the Germans adapted the shock tactics to modern mechanized warfare. The Blitzkrieg was a shock tactic based on tanks which gained considerable achievements during the war and was afterwards adopted by most modern armies.
