Blitzkrieg (German, lightning war listen is an anglicised word describing allmotorised force concentration of tanks, infantry, artillery, combat engineers and air power, concentrating overwhelming force at high speed to break through enemy lines, and, once the lines are broken, proceeding without regard to its flank. Through constant motion, the blitzkrieg attempts to keep its enemy offbalance, making it difficult to respond effectively at any given point before the front has already moved on. During the interwar period, aircraft and tank technologies matured and were combined with systematic application of the German tactics of infiltration and bypassing of enemy strong points.
