Sergeant Oren Talle
Runs the Training Grounds
“I don't bite. The bots do.”
Three exams stand between a cadet and their rank, and all three are his. He will be on the PA for every one of them, telling you what you did wrong before you have finished doing it.
He calls everyone Cadet until they have earned something better, and he has never once sworn on duty. The bots give him every reason to.
