Answer:
Executive Branch
Step-by-step explanation:
In the United States, the branch of government that is in charge of the military is the Executive Branch, specifically the President of the United States, who is the Commander-in-Chief of the armed forces. However, the legislative branch, specifically the Congress, has the power to declare war, raise and support armies, and make rules governing the military. So, while the President is in charge of the military, the Congress has an important role in overseeing and regulating the military's activities.
