German Tanks
PzKpfw VI "Tiger"

The Panzerkampfwagen VI "Tiger" was the most feared allied tank of the Second World War. Its KwK 36 L/56 88mm gun could knock out tanks at ranges of up to four kilometers. The armour was excellent for the majority of the war, with 100mm hull front and 120mm turret front; it could only be killed by late-war Allied tanks like the M26 Pershing. Its weaknesses were it being to heavy so that it was slow and it couldn't cross bridges because they would collapse. It was also over engineered, only 1,347 Tigers during the whole war were made were made and in one year 11,778 T-34/85s were made in the Soviet Union.
PzKpfw V "Panther"

The Panzerkampfwagen V "Panther" was the only German tank to include speed, armour and firepower in balance. Its cannon the KwK 42 L/70 75cm cannon was better than the Shermans and it took until 1944 for the Allied tanks to get an equal gun to it. It was the first German tank to have sloped armour and that was also put on the PzKpfw VIB "Tiger II". The side armour was 50mm thick; a big weak point. About 6,000 Panthers were made.
PzKpfw IV

The Panzerkampfwagen IV was the main Wehrmacht tank of World War II. Development of this tank started in 1934 and the tank stayed in production until 1945; long service for a tank developed in 1934. Originally meant to be a bunker buster, it ended up being up-gunned for anti-tank operations. It had many upgrades over its service in the Wehrmacht. Its armour was adequate, on later versions 80mm of frontal hull armour. Its gun had a 500m range; while it enemy, the Sherman, had only 200m range. There were some plans to put the Panther turret with the KwK 42 L/70 75mm cannon on it but it failed because it was to heavy for the suspension. The PzKpfw IV here is the Ausf H variant with side skirts on the turret and hull.
Sturmgeschütz III (StuG III)

The StuG III was meant as a infantry support vehicle and a bunker buster to help infantry (explains why it was equipped with a bunker buster gun for that period of time. The StuG has good armour and goes quite fast (it would need it because it doesn't have a turret) which makes it a good vehicle. Its gun was upgraded over time until it had the KwK 40 L/48 75mm cannon. It served with the Wehrmacht for the entirety of the war. This is the StuG Ausf G with the KwK 40 L/48 75mm cannon.
