Final answer:
The document or system that provides Air Staff and Air Force Commanders with the necessary information for wartime operations is a comprehensive military strategic plan, which is likely influenced by the Joint Chiefs of Staff and other military and civilian defense leaders.
Step-by-step explanation:
The document or system that provides Air Staff and Air Force Commanders with current policies, planning factors, and forces for conducting and supporting wartime operations is likely to be part of a comprehensive military strategic plan. This includes the Joint Chiefs of Staff, who oversee various elements of the U.S. armed forces, including the Air Force. They work alongside other senior military and civilian leaders to ensure that all facets of military readiness are aligned with national security objectives. High-level strategic guidance typically comes from documents such as the National Security Strategy or specific military planning and policy guidance from the Department of Defense.
In the context of history, looking at the situation during World War II for example, the general staff and military planners, such as those serving under leaders like Dwight D. Eisenhower, were responsible for the orchestration of multi-theater operations and coordination of military efforts. After WWII, organizations and roles evolved with the creation of the independent United States Air Force and the development of modern military structures and comprehensive planning systems.
Today, this also involves collaboration with various elements of the government, like the National Security Council, the CIA, and the Director of National Intelligence, to create integrated military plans that are capable of responding to contemporary warfare challenges.
