Which personnel must be licensed on all equipment and vehicles in accordance with AR?

All crew members are required to be licensed on all equipment and vehicles in accordance with Army Regulation (AR). This regulation emphasizes that proficiency in operation and safety of vehicles and equipment is critical for all personnel who may be tasked with operating them. Licensing is essential to ensure that all crew members possess the necessary knowledge and skills to operate the equipment efficiently, safely, and in compliance with established protocols. This comprehensive understanding among the entire crew enhances operational readiness and minimizes the risk of accidents or malfunctions during missions.

The other roles mentioned, while important in their own right, do not encompass the entire scope of responsibility for operating military vehicles and equipment as fundamentally as crew members do. Their training and oversight are crucial, but they do not replace the necessity for every individual who is part of the crew to have the requisite licensing.
