Rangemaster

The Rangemaster is a teacher at Rommelwood Military School.

History
He gave a fearsome-looking grenade launcher to Bart, because he concluded that Bart can use small arms, according to attending public school. Bart was very well at shooting and the rangemaster praised him.

However, Lisa had many problems with shooting. She somehow got her rifle stuck on "auto-fire" and could not stop it. The rangemaster helped her and gave to her a whistle. He told her that if she blows on it, he will come help her
