Final answer:
The exact timeframe within which subordinate commanders must notify airmen of taskings received 30 days or more before RDD is not provided in the question. However, similar protocols, like the President's deployment of troops, require notification to Congress within 48 hours and Congressional approval for deployments beyond 60 days.
Step-by-step explanation:
The question centers around a specific military protocol regarding the notification of taskings. When tastings are received 30 days or more prior to RDD (Required Delivery Date), subordinate commanders are obligated to notify their airmen of the tasking. The information provided, however, does not include the exact timeframe within which subordinate commanders must notify their airmen about the tasking when it falls under these conditions. In a related note regarding the deployment of troops, the president of the United States does have the authority to deploy troops to other countries for hostile reasons. However, in accordance with the War Powers Resolution, the president must notify Congress within 48 hours of committing armed forces to military action and, barring Congressional authorization, must end the deployment within 60 days. If RDD and Airment are specific terms used within a certain organization or field, I recommend consulting the relevant organizational documents, manuals, or contacting the appropriate authorities within that context for accurate and up-to-date information.
