What are the two main objectives of sustainment training?

The two main objectives of sustainment training focus on the practical application of skills and knowledge to ensure effective mission readiness. Training on known tasks and honing proficiency is crucial because it emphasizes the need to maintain and improve the skills that soldiers have already acquired. This ensures that personnel can perform their duties consistently and efficiently under different conditions, thereby enhancing overall operational effectiveness.

While the other options contain elements of training evaluation and knowledge enhancement, they do not encapsulate the primary focus on the continuation and refinement of skills and tasks—essential aspects of sustainment training that support mission success. By honing proficiency, soldiers can better adapt to new challenges and sustain high levels of performance in tactical environments. Thus, this focus on maintaining and improving existing skills aligns closely with the overarching objectives of sustainment training.
