Which of these is NOT typically included in a training regimen for JITTS?

In the context of a training regimen for Just-in-Time Tactical Training Systems (JITTS), field exercises are typically a vital component. They are designed to simulate real-life scenarios that personnel may encounter, allowing them to practice and refine their tactical skills in a controlled environment.

The inclusion of stretching is important for maintaining flexibility and preventing injuries during physical training, while injury assessment is crucial for ensuring the safety and readiness of personnel. The option of "tap out," which often refers to a practice used in grappling and martial arts to indicate submission, is also part of many training regimens focused on combat readiness.

By contrast, field exercises may not represent a part of a strict training regimen specifically designed for JITTS, which tends to focus more on individual skills and immediate tactical applications rather than the broader, group-based scenarios typically associated with field exercises. This makes "field exercises" the best option for what is not typically included in a JITTS training regimen.
