AT guns

Historical facts
After the first usage of tanks in World War I by the allied forces in France/Belgium the war machinary needed an effective weapon against these metallic "boxes". The first idea was to use oversized rifles with heavy steel rounds which were sometimes able to break through the tank's armor. But with these weapons became uneffective with the time because of the growing up level of armor of the tanks.

This problem made the developers of weaponairy think about a new solution. In World War II the main and most effective weapon against tanks was the AT-Gun. The Germans built it in over 5 different versions during the war, the most popular one was the Panzerabwehrkanone (PAK) '40 (ger. Anti-Tank Defense Gun '40). The United States and the United Kingdom built 4 different versions each. France only built one version which was used by the German occupiers later as: 2,5cm PAK-113(f).

In Game
Anti-tank guns are much more effective against vehicles than they are effective against Infantry. Make sure that the flancs are secure before you place them anywhere at the frontline. AT guns only have 3 disadvantages:
 * 1) The slow movement speed - Tip: Place them somewhere on a central position where you can move them to any frontline part on the map.
 * 2) The limited fire sector - Tip: Do not place them directly in the first line of your defences. You should give them a position between covers and behind infantry units, so that the enemy is not able to flanc, or even to capture them.
 * 3) The high vulnerability from behind and from above - Tip: Give them Infantry support. Never let them defense an area by themselves. Also place them out of enemy artillery range.
