Based on the type of organization, these collective exercises are evaluated to standard leader and trainer after-action reviews. Objective evaluations of both individual and unit proficiency provide both readiness indicators and future training requirements. Leader courses and unit publications are designed to develop the officer and NCO proficiencies necessary to plan and conduct marksmanship training and evaluate the effectiveness of unit marksmanship programs. Training support materials are provided by the proponent schools. FM 23-27 is organized to lead the trainer in a progressive manner through the material needed to aid him in training units.
Information is presented beginning with preliminary subjects.
These include mechanical training, knowledge of the gun's capabilities, and the principles and fundamentals of MK 19 gunnery. Live-fire applications are scheduled after the soldier has demonstrated these preliminary skills. Initial firing will be an instructional exercise, which ultimately leads to the soldier's ability to target the MK 19. Targets and target scenarios of increasing difficulty are mastered to develop proficiency. This progression and the targets are outlined in Appendix C .
