Btitish Mk 1
First tank developed and used in combat. Was capable of crossing trenches and providing support for infantry. Replaced the need for calvalry (horses) thus bringing in the term armored calvary. https://en.wikipedia.org/wiki/British_heavy_tanks_of_World_War_I -
French Renault FT
First tank to incorporate a turet for the main armament. This inovation gave the tank more manuverability and did not place the gun in a fixed position. If the tracks were blown off it would still be able to acuire targets in all directions. https://en.wikipedia.org/wiki/Renault_FT -
French Schnieder CA1
First tank have sloping of frontal glacis. This sloping of the armor made it harder for a shell to penetrate its armor. The greater the slope the higher chance of a ricochet. https://en.wikipedia.org/wiki/Schneider_CA1 -
German A7V
The need to counter the British Mk 1 led to the developement of the A7V for the western front during ww1. Not extremely important in terms of inovation but a real milestone for the nation that would soon become the best at tank building. https://en.wikipedia.org/wiki/A7V -
French SOMUA S-35
First tank to fully incorporate slopped armor. As previosly stated this inovation made a tank harder to kill and thus increased its survivability. https://en.wikipedia.org/wiki/SOMUA_S35 -
German Tiger 1 Ausf H
First tank to be equiped with the 88mm Flak gun. This was the largest gun to be ever fitted on a tank. The whole chasis was built around this gun. With a penetration value up to 237mm this gun packed quite a punch. https://en.wikipedia.org/wiki/Tiger_I -
German Panzer 4 Ausf H
One of the first tanks to be equiped with side skirts. These skirts negated the effect of HE rounds. They were basically sacrificial plates of armor that detonated the round and diffused its concentrated jet that it relied upon for penetration. https://en.wikipedia.org/wiki/Panzer_IV -
Explosive Reaction Armor
1949 was the first year that the developement of this armor started. The basic concept was that when a shaped charge hit the armor it would detonated and have enough force to prevent the shell from penetrating the armor. https://en.wikipedia.org/wiki/Reactive_armour
