Which of the following is NOT one of the five phases of basic rifle marksmanship (BRM) training?

The correct answer highlights that "Advanced Field Tactics" is not one of the five phases of basic rifle marksmanship (BRM) training. The five phases are focused on developing foundational skills necessary for effective marksmanship, which include the fundamental techniques of shooting, target engagement, and transitioning from basic to more advanced levels of firing.

"Preliminary Marksmanship Instruction," "Downrange feedback range firing," and "Field firing" are all established parts of the BRM training process. They address various aspects of marksmanship, from initial instruction to practical application in realistic environments, ensuring soldiers are well-prepared to engage effectively.

In contrast, "Advanced Field Tactics" falls outside the scope of basic rifle marksmanship as it focuses more on complex combat scenarios and strategies rather than the fundamental skills of marksmanship. This distinction clarifies the structure of the training and the objective of each phase, reinforcing why this choice is the correct answer.
