Final answer:
When a command security officer is absent, his duties are commonly deferred to the commanding officer and the executive officer, but this can vary depending on an organization's specific protocols.
Step-by-step explanation:
When a command security officer is absent, his duties and responsibilities should typically be deferred to the commanding officer and the executive officer. However, it's crucial to refer to specific organizational protocols as these can vary depending on the organization's structure and regulations.
The command security officer is responsible for the overall physical, information, and personnel security programs within the command. These duties are quite sensitive and critical to the functioning of the command, hence the reason they generally fall to the senior-most officers like the commanding and executive officers in the absence of the dedicated security officer. The commanding officer ultimately holds the responsibility for all that transpires within their command, while the executive officer supports the commanding officer in administering the unit.
It's important to note that different military organizations and units might have varying policies on the chain of command and delegation of responsibilities; thus, always consult the specific command's protocols or standard operating procedures for definitive guidance on this matter.
