Command & Conquer: Red Alert 2 Glitches

Duplicate soldiers
If you have a cloning vat and have captured a hospital sending wounded soldiers into the hospital will duplicate the soldier from the cloning vat and furthermore if you have entered a spy into a barracks then the duplicated ones will be veteran this will work with soldiers that can only be built once like Yuri Prime and thus you can create an army from 1 soldier and something to hurt it like a conscript and it does not cost much to repair soldiers.
(Does not work with tanks and a service depot)
