FM 3-22.9 (FM 23-9) Rifle Marksmanship M16A1, M16A2-3, M16A4, and M4 Carbine MANUAL By

An effective unit marksmanship program reflects the priority, emphasis, and interest of commanders and trainers. This chapter provides a proven rifle marksmanship training strategy as guidance in establishing and conducting an effective training program. The strategy consists of the progressive individual training periods taught during initial entry training (IET). It progresses into advanced skills and concludes with advanced reading material. Refresher training need only be conducted on periods that are deemed necessary. The proficiency attained by a soldier depends on proper training and application of the basic marksmanship fundamentals. During initial marksmanship training, emphasis is on learning the firing fundamentals, which are taught in four phases-preliminary rifle instruction, downrange feedback, field firing, and advanced firing exercises. This prepares soldiers for advanced optic and laser training for combat-type collective exercises and real world deployments.
