That is a straight up fact, we as instructors train all the time even if the training is redundant. Case in point I am scheduled to attend a red dot instructor class with Don Edwards (you likely know him) of Greenline Tactical. While I already hold a red dot instructor tab the tactics and methodology of red dot is an ever changing landscape due to the rapid advances in technology on the platform. In addition he has added Jon Jeu to his cadre of instructors, I have trained and sweated with Jon a time or two, he was one of the marksmanship coachs for US Marksmanship Team. In fact he is at the world sniper competition this week. Well…..and I do like sipping Bourbon with Don!
