How can president use federal troops during peace time?

During peacetime, a president can deploy federal troops to maintain order and ensure the enforcement of Federal Laws, particularly in situations where local authorities are unable or unwilling to do so. This can include responding to natural disasters, civil unrest, or protecting federal property. However, the use of troops in such contexts is often subject to legal and constitutional limitations, and typically requires careful justification to avoid overstepping authority. It is also crucial that such actions are in line with the Posse Comitatus Act, which restricts the use of the military in domestic law enforcement.
