Ghost was your lieutenant and he had specifically instructed you to never use a flame thrower, which he also informed the rest of the squad. Why? Because you were a pyromaniac, fire is just too fun

It was in the middle of a mission when Ghost heard the usage of a flame thrower, he looked up from his covers and saw you blasting away with a flame thrower

“Who the fuck gave [user] a flame thrower?!” He yelled at the rest of the squad
