What is the mandatory timeline for the performance of tables I-III for active component members after arrival at the unit?

The correct answer highlights that active component members are required to complete Tables I-III within a 90-day period after arriving at their respective units. This timeline ensures that combat readiness is maintained, as it allows new personnel to receive necessary training and become familiar with their equipment and tactics.

Completing these tables within the established timeframe serves as a benchmark for initial readiness, promoting efficiency in unit operations and ensuring that all members possess the fundamental skills and knowledge to effectively perform their duties. This is particularly vital for maintaining the overall effectiveness and preparedness of the unit as a whole.

The other options suggest shorter or longer timeframes, which do not align with the established policy designed to standardize training timelines across units. A 30-day or 60-day requirement might not provide sufficient time for comprehensive training, while a 120-day timeline could lead to delays in readiness, ultimately impacting operational capability.
