What principle of training focuses on preparing soldiers to be proficient in using their equipment?

The principle of training that emphasizes preparing soldiers to be proficient in using their equipment is focused on the importance of ensuring that service members have the necessary skills and knowledge to operate their tools effectively. This aspect of training encompasses understanding not just how to use the equipment, but also knowing how to maintain and troubleshoot it during operations.

By concentrating on this principle, soldiers can develop a deeper level of expertise, which is critical in high-pressure situations where immediate familiarity with their equipment can be the difference between mission success and failure. This training ensures that soldiers are not only able to operate their equipment but also equipped to perform essential maintenance tasks, thus enhancing their reliability and overall operational performance.

In contrast, the other principles revolve around different aspects of training, such as achieving success in missions, sustaining skills over time, and training in conditions that mirror real-world scenarios. While these are all vital components of military training, the emphasis on proficiency with equipment specifically identifies the capability to effectively handle and maintain that equipment as a core focus, which is integral to mission readiness.
