Factual error: The tank used by the German platoon is a Soviet T54/55, which didn't come into service until 1948, after the Lapland War had ended.
Character mistake: Near the ending of the movie, when Aatami slips with his pickaxe under the plane, they hear a noise inside the plane and ignore the noise by saying it's just an old plane. The DC-3 was actually only 8 years old and still in production by the time setting of the movie, which doesn't make it really that old. (01:13:23)
