You may prorate the following training tasks EXCEPT:

Prorating training tasks refers to adjusting training hours or times based on the actual needs or circumstances relevant to the individuals involved. This requires understanding which tasks can be adjusted and how they contribute to overall training goals.

Small arms training typically involves extensive hands-on instruction that is crucial for ensuring safety, proficiency, and compliance with regulatory standards. Because this type of training is highly specialized and often mandated by military regulations or safety protocols, it cannot be prorated. This ensures that every participant receives the full foundation necessary to handle firearms responsibly and effectively.

In contrast, other training types like flight simulator training, ground training, and specialized technical training may have more flexible structures, allowing for adjustments based on individual performance, experience levels, or specific objectives. This flexibility facilitates tailored learning experiences that can be optimized for the needs of different trainees, which is not as feasible with small arms training where comprehensive exposure and practice are vital.

Thus, the essence of the training requirements and the critical nature of safety measures associated with small arms distinguish it as a task where prorating is not permitted.
