Germany concentrated its tanks into panzer divisions during World War II to serve as a decisive, self-contained striking force capable of executing the blitzkrieg doctrine.12

Rather than dispersing tanks among infantry or cavalry units, the German military massed them to achieve a Schwerpunkt—a "center of gravity" or point of concentrated force. This approach allowed the German army to:34

  • Create Breakthroughs: By concentrating firepower at a specific point, they could penetrate enemy defensive lines effectively.24
  • Exploit Mobility: Once a breach was made, these mobile, combined-arms divisions—which included motorized infantry, artillery, and engineers—could bypass obstacles, penetrate deep into the enemy's rear, and disrupt communications and administration.24
  • Induce Psychological Shock: The speed and coordination of these massed formations were designed to paralyze the enemy's ability to organize a defense, leading to rapid collapse.24

By integrating tanks with other support elements and utilizing advanced radio communications, the panzer division became a highly efficient, elite unit that prioritized offensive maneuver over static defense.124
