Dumb Unit/Building Ideas

List any unit/building ideas that would break the game but would be fun to have anyways. They can be joke units. Here are mine:

ICBM: Nuke but with unlimited range and increased damage.

Super-Heavy Tank: Historically accurate mega tank. Basically a Maus. Counters Heavy Tanks.

Super-Duper Heavy Tank: Historically accurate mega-mega tank. It is called the Landkreuzer p. 1000 Ratte. Counters Super-Heavy Tanks.

Aerial Refueling Aircraft: Non-historically accurate for world war 2 but what if you could refuel your rocket fighters mid air?

Gulags: You can build concentration camps in occupied enemy territory to decrease the morale of the enemy nation. Maxed Gulags instantly send all enemy armies to Brazil.

Mines: You can plant mines in your territory and when a unit hits it they take damage. Would be very useful for people using the turtling strategy.

Transport Planes: Carry your units at high speed in the air instead of on the ground. Units are extremely vulnerable when being transported like this.

Unit Suicide/Kamikaze: Upon activation, your units will get increased stats but in return will die after attacking. Damage is significantly increased for Pan-Asian doctrine.

Wind Cannon: Historically accurate. Wind pushes units away from the cannon.
