Miris a Russian space station used by the Russian Federation as a weaponised spacecraft against the invading Nazi forces. Mir had a particle weapon as it's main weapon, and was seen firing it at a Siegfried-Class Warship during the battle.
Behind the scenesEdit
The real-life Mir was de-orbited and destroyed in 2001. This is referenced in the movie, with the President of America being surprised by Mir joining the battle. Mir in the film was visually quite different to its real-life counterpart, and may have either been modified or rebuilt.
