The Middle-Son 1986 is a naval vehicle from the Regular Army or Rebel Army.


The Middle-Son 1986 is an old U-Boat submarine used by the Regular Army. Even though a more advanced variant was created, it is still used frequently, even though it's very outdated. It can carry a lot of weapons such as missiles and torpedoes, and has an anti-aerial machine-gun turret on its hull. Its impressive HP is very outstanding able the army or players to stand still even bombs are exploding and the turret as a support mechanism. This boat is only used to transport the Regular Army to the other side of the Straits of Traven, where the Rebel Army leader General Morden awaits.


  • It is based off a German U-Boat or the USS "Gato" Class Submarine.
  • It is unknown if the number indicates it was constructed in the 1980s or otherwise.
