Add-on Armor is a modification in-game that allows the player to enable the addition of improvised armor onto their tanks.

History

Tank warfare is a type of battle that can make the equipment involved become obsolete very quickly in terms of protection and firepower. In World War II, this is seen especially in the later half of the war when the Shermans and T-34s began being outgunned by better German tanks, and the German Panzer IV also being outgunned by those tanks. In an effort to get more protection onto their tanks, crew often improvise a variety of methods to increased the armor on their tanks. Methods included welding tracks or sheet metals as appliqué armor onto the tanks, placing sand bags on the hull, hanging logs from the sides, placing mesh sheets, or simply just pour concrete on the hull for the thickness. While these protection vary in their ability to stop a penetrating round or warhead, they all increase the overall weight of the tank, often taxing the suspension and steering beyond their normal capabilities. General George S. Patton, commander of the U.S. Third Army during the invasion of France, heard of this effect of improvised armor on the tank's suspension and forbid his tank units from using the common sandbags as improvised armor to mitigate vehicle breakdowns (he was however a fan of welded metal sheets similar to the M4A3E2 Jumbo and had many normal Shermans made into make-shift Jumbos).

Results vary from the variety of improvised armor used in the war. Some armor, like the concrete, was deemed useless or impractical and were not widely used. Sandbags and logs was actually seen as ineffective against the tank rounds and HEAT warheads used by infantry anti-tank launchers. Out of the bunch, welded metal was perhaps the most effective improvised armor one can put onto a tank. A study done by the U.S. Army on the improvised armor used by the tankers on their Shermans reveal that while the majority of improvised armor had little effect on armor protection, the best impact of improvised armor was morale, as they at least gave the worried tankers an additional bit of protection for their tanks.

Effect in-game

In the game, the Add-on Armor modification adds spare track links along the hull and turret of the tank being modified. The track links, when added, give an around 17 - 20 mm of additional armor to where they are attached.

As of 1.67, the add-on armour now adds mass to the overall vehicle weight, meaning a lower power-to-weight ratio and thus lower mobility.
