What is the main benefit of including sustainment training in marksmanship?

The main benefit of including sustainment training in marksmanship is to maintain previously acquired skills. Sustainment training is designed to ensure that soldiers retain the proficiency and competence they have developed during initial training. Marksmanship skills can degrade over time if not practiced regularly; therefore, sustainment training provides the ongoing practice needed to keep these skills sharp.

By focusing on the maintenance of skills, this type of training allows personnel to respond effectively and confidently in real-world situations where marksmanship is critical. It ensures that individuals can quickly recall techniques, apply them in various contexts, and demonstrate consistent performance under pressure. This consistency is vital for mission success, particularly in combat scenarios, where precision and timing can be the difference between success and failure.
