Goofs

During the big fight (near end), when the police are hiding inside a home and spot Martin, the shot we see of Martin has his right arm completely covered in blood (no skin colour visible) but in the next shots the same arm is practically clean, with only a few smears of blood.

Tiger tank's four petrol tanks are located in the back, two at each side of the engine compartment, not under the radio-operator's escape hatch like shown in the movie.

Even with full petrol tanks (540 liters), the Tiger had an operational range of 195km on road and 100 kilometers off road before refueling.

The Nazizombies are taking Diesel from the touring car to put in the Tiger tank. Tiger tanks ran on Petrol, not Diesel. It would be nearly impossible to start the engine and if that somehow would succeed, it would not run smoothly.

Some of the Nazi soldiers are wearing camouflage, instead of the traditional WW2 uniforms. Whilst looking modern, the German army used camouflage uniforms as early as 1937, and the uniforms used in the movie is most likely Waffen-SS Platanenmuster or Erbsenmuster pattern.

In the hospital, the police say that Martin's fingerprints were found on the ax that killed his girlfriend. But the doctors reattached the arm that belonged to Herzog, so the prints would not have matched.

NOT A GOOF: Martin killed his girlfriend in the first film, even before amputating his own arm, so his fingerprints would indeed be on the ax handle.

Hanna's age stated in the newspaper which Martin read was 30. But her gravestone marked with 06.12.1987 - 13.04.2013 which makes her 25 years old at her time of death.

The Nazi-zombies took the tank from a WW2-museum. Where did they get the shells that they were firing later in the movie? It is highly unlikely that the museum had live tank-shells in their exhibition.

The Soviet zombies all lose their power when the Soviet commander is killed. But the Soviet zombies were resurrected by Martin, so they should be tied to Martin.

The Soviet zombies don't lose their power when their leader is killed. They were already outnumbered and losing the fight before he died.

In the museum scene, when Martin is reading a card on Colonel Herzog, the ship Herzog was inspecting is identified as "Scharnolsht", which Glenn corrects to "Scharnholst". Both names are incorrect, the actual name of the ship was "Scharnhorst", named after Napoleonic Wars-era Prussian general Gerhard von Scharnhorst.
