Blitzkrieg or Bewegungskrieg is a word used to describe a combined arms surprise attack using a rapid, overwhelming force concentration that may consist of armored and motorized or mechanized infantry formations; together with artillery, air assault, and close air support; with intent to break through the opponent's lines of defense, dislocate the defenders, unbalance the enemies by making it difficult to respond to the continuously changing front, and defeat them in a decisive Vernichtungsschlacht: a battle of annihilation.

Combined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects—for example, using infantry and armour in an urban environment in which each supports the other.
