Trivia: Minor Spoilers for "Cult of Chucky." Series creator Don Mancini's original idea for "Child's Play 3" included multiple Chuckies. When Chucky's blood is accidentally mixed into the molten plastic, every single doll the assembly line produced was going to be possessed by Chucky's spirit. The idea was dropped for time and budgetary reasons, so only the first doll produced had his soul inside of it. Mancini always loved the idea, and was later able to implement a variation of it in the seventh film, "Cult of Chucky." (Although in that film, Chucky is able to possess multiple hosts at the same time thanks to a spell that more-or-less copy/pastes his spirit).

Question: When Chucky is loading the guns with real ammo instead of paint, why would a military school store or even use live rounds?
