Which statement best describes sustainment drills in training?

• A. They are one-time activities.
• B. They replace the need for supervision.
• C. They reinforce skills to reflexive levels.
• D. They are irrelevant to belt progression.

Answer: (C)

Sustainment drills are ongoing, focused practice designed to keep skills at a high, automatic level. The best description is that they reinforce techniques to reflexive performance through repetition under realistic conditions, so you can execute them smoothly and without conscious thought even when tired or pressured. This automaticity is what sustainment drills aim for: skills stay sharp, transfer to real-life scenarios, and remain ready for longer periods.

They aren’t one-time activities, and supervision is still important to ensure correct form and safety. They also support belt progression by maintaining the proficiency that higher belts expect, rather than being irrelevant to advancement.
