Localized training alarm monitors must be approved by which entity?

The correct answer is the Major Command. Approval of localized training alarm monitors is crucial for ensuring safety and compliance with established procedures and standards within the military environment. Major Command is responsible for overseeing and coordinating operations within a specific area or function, which includes setting the standards for training and safety protocols. Their approval ensures that the training alarm monitors meet the necessary guidelines and that they are compatible with broader operational standards, facilitating effective training without compromising security or safety.

The Base Commander and Security Forces Leadership may have roles in monitoring and enforcing standards at their respective levels, but major command has the authority and responsibility to approve training alarms on a wider scale. The Training Department may also play a role in implementing training programs, but the final authority typically rests with Major Command, thus making it the appropriate entity for approval in this context.
