What is sustainment?

• A. A temporary drill that resets skills after one session.
• B. Reinforcing learned skills until they become reflexive through repetition.
• C. A one-time practice focusing on new techniques.
• D. A theoretical concept with no practice.

Answer: (B)

Sustainment means continuing to reinforce and practice skills after they’re learned so they become reflexive. It involves regular, deliberate repetition over time, often with spaced practice and varied contexts, to maintain proficiency and build muscle memory. This keeps techniques sharp between training cycles and under fatigue or stress. It isn’t a one-off drill, nor a theoretical concept, and it isn’t about learning something new in a single session. It’s about preserving and solidifying what you’ve already acquired through ongoing practice.
