The advanced development and sustainment phase is focused on both maintaining the skills and competencies that have already been mastered while simultaneously introducing new tasks and concepts to enhance an individual’s capabilities. This phase is critical for ensuring that trained personnel remain proficient in their existing skills, which is essential for operational effectiveness, while also preparing them to adapt to new challenges and requirements that they may encounter in the field.
In this context, the emphasis on sustaining mastered tasks ensures that personnel do not fall out of practice, which can lead to skills degradation. Furthermore, by developing new tasks, the training remains relevant and aligned with evolving operational needs or technological advancements. This dual approach not only enhances individual performance but also contributes to overall unit readiness and effectiveness.
The other options do not fully capture the essence of this phase. Focusing solely on learning new concepts neglects the importance of sustaining existing skills. Evaluating past training success and assessing performance capabilities, while important aspects of training and development, do not encompass the active involvement in both sustaining and developing skills that define the advanced development and sustainment phase.
