Final answer:
The exchange or transfer of an enlisted person's uniform is governed by military regulations and typically handled by lower-ranking officers or officials, not directly by the President.
Step-by-step explanation:
The authorization for the transfer or exchange of an enlisted person's uniform is typically within the purview of military regulations and policies set by the Department of Defense. There is no direct indication that such a specific task as the exchange of a uniform is the responsibility of the President of the United States, despite the President's role as Commander in Chief of the military. While the President has the overall command and authority over the military, the day-to-day decisions and administrative duties, such as uniform exchange, are generally handled by lower-ranking officers or officials according to the guidelines of the military branch concerned.
