Which phase is NOT one of the five phases of rifle marksmanship?

The five phases of rifle marksmanship in the Army specifically include Basic Rifle Marksmanship (BRM) training components that are designed to progressively develop a soldier's shooting skills. These phases typically involve training in controlled environments and then moving to increasingly challenging settings, ultimately preparing soldiers for various combat scenarios.

The option regarding BRM Long Range Firing is not considered one of these established core phases. Instead, the recognized phases focus primarily on foundational training, practical exercises in the field, and advanced techniques, rather than specifically designating long-range firing as a distinct category within the basic training structure.

Each of the other options represents essential components of the broader rifle marksmanship training framework. Generally, ARM (Army Marksmanship Qualification) is part of the overall qualification process, while advanced techniques involving optics, lasers, and iron sights represent the evolution of marksmanship skills beyond basic training. BRM Field firing is an essential practical application phase where soldiers apply their learned marksmanship skills in realistic scenarios. This categorization helps ensure that basic skills are mastered before soldiers advance to more specialized techniques and equipment.
