What contributes to a rifleman's effectiveness according to ATP 3-21.8?

The effectiveness of a rifleman is fundamentally rooted in their ability to engage targets accurately and decisively, which is encapsulated in the mastery of delivering well-aimed shots. According to ATP 3-21.8, the core competencies expected of a rifleman center around marksmanship skills. This includes not only knowing how to fire a weapon but also critically assessing the range, understanding the effects of wind and other environmental factors on a bullet's trajectory, and making necessary adjustments for precise shooting.

Engaging targets with well-aimed shots is essential for maximizing effectiveness in combat situations, as it directly impacts mission success, the safety of personnel, and overall operational efficiency. The focus is on skillful engagement rather than on ancillary skills not related to direct combat performance, such as culinary skills, weather forecasting, or financial management. These skills do not have a bearing on a rifleman's primary responsibilities during operations, highlighting why they are not relevant in this context.
