How will the commander or SAO endorse all mail for a deceased individual?

The endorsement of all mail for a deceased individual is performed using the endorsement "DECEASED." This method of endorsement is important as it clearly indicates the status of the individual to whom the mail is addressed, ensuring that postal services and other relevant parties can recognize that the recipient is no longer living. This helps in managing mail appropriately, including honoring requests for redirection or returning mail that cannot be delivered to a deceased individual.

Using the "DECEASED" endorsement is an official procedure that communicates the necessary information succinctly and formally, aligning with regulations that govern handling mail for deceased persons. The other options, while they might include gestures of respect or formality, do not serve the specific function of clearly notifying recipients and postal workers of the individual's passing in a standardized way.
