What military power does the president have regarding troop deployment?

The president possesses significant authority in managing military operations, including the deployment of troops. Specifically, the president can send troops into combat or deploy military forces without needing prior congressional approval. This power is rooted in the role of the president as Commander in Chief of the armed forces, a position established by the Constitution.

This authority allows the president to respond quickly to emergencies, threats, or military needs that may arise without the delay of seeking legislative consent. However, while the president has the power to deploy troops, the War Powers Resolution of 1973 does require that the president notify Congress within 48 hours of sending troops into hostilities and limits the engagement to 60 days, with a further 30-day withdrawal period unless Congress grants approval for a longer deployment. Thus, while the president can act unilaterally in certain circumstances, there are still checks in place to ensure congressional oversight over military actions.
