A more thorough explanation:

The Commander in Chief powers refer to the authority given to the President of the United States to lead the military forces of the country. According to Article II Section 2 of the U.S. Constitution, the President is the Commander in Chief of the Army, Navy, and Militia of the United States. However, the extent of the President's powers as Commander in Chief has been a subject of debate throughout American history.

One example of this debate is the War Powers Resolution, which was passed by Congress in 1973 to limit the President's ability to commit U.S. troops to military action without Congressional approval. The resolution requires the President to notify Congress within 48 hours of committing troops and to remove them after 60 days if Congress does not grant an extension. However, Presidents have typically considered the resolution to be unconstitutional and have not followed it.

Another example of the Commander in Chief powers is the Authorization for Use of Military Force against Terrorists (AUMF), which was passed by Congress after the September 11 attacks. The AUMF authorized the President to use "all necessary and appropriate force" against those responsible for the attacks. This gave the President more authority to exercise his constitutional powers as Commander in Chief.

However, the use of the Commander in Chief powers has also been controversial, particularly in relation to the treatment of detainees at Guantanamo Bay. The Supreme Court has ruled on several cases related to the detention of prisoners at Guantanamo, including Rasul v. Bush and Hamdan v. Rumsfeld. These cases have addressed the extent of the President's powers as Commander in Chief and the rights of detainees under the U.S. Constitution.

Overall, the Commander in Chief powers are an important aspect of the U.S. Constitution and have been the subject of much debate and controversy throughout American history.
