Which principle of training emphasizes maintaining proficiency over time?

The principle of training that emphasizes maintaining proficiency over time is "Train to maintain." This principle is essential because it focuses on the need for Soldiers to retain the skills and knowledge they have acquired through training. Proficiency is not just achieved; it also requires ongoing practice and reinforcement to prevent skill degradation over time.

This principle acknowledges that Soldiers need to engage in regular training activities to keep their skills sharp, ensuring that they can perform effectively when called upon in real-world situations. It highlights the importance of continuous learning and practice, particularly in dynamic environments where conditions may change and new tactics or technologies emerge.

In contrast, other principles may focus on different aspects of military training. "Train as you fight" emphasizes realistic training that simulates battlefield conditions, while "Train to standard" stresses meeting specific performance criteria. "Train combined arms" relates to integrating various military disciplines to work together effectively. While all these principles are valuable, "Train to maintain" uniquely highlights the necessity of ongoing proficiency, making it the correct choice in this context.
