During W.W II the German military made extensive use of radio. One of the key elements of the Blitzkrieg was the co-ordination of armour, air power, artillery and infantry, and radio was the perfect medium for this co-ordination. The German victory over Poland in 1939 illustrated how intermedate communication between land and air units could more effectively defeat an enemy. However, it was the success of the panzer troops in France and Russia that showed how indispensable radio had become in armoured warfare. A brief review of their opponents' failures will help to show the advantage radio gave to the German panzers.
