Final answer:
The company commander decides if the shortages are legitimate during a training event.
Step-by-step explanation:
In the context of a training event, when shortages are discovered, the responsibility of deciding if the shortages are legitimate falls on the Company commander. The company commander is the highest-ranking officer in the company and has the authority to assess and determine the legitimacy of the shortages.
The Range Ammunition NCO (Non-Commissioned Officer) is responsible for managing and maintaining the range ammunition. While they may offer input, the final decision rests with the company commander.
Unit personnel and ASP (Ammunition Supply Point) personnel may be involved in the process of reporting and investigating shortages, but they do not have the authority to independently decide if the shortages are legitimate or not.
