The U.S. Constitution establishes provisions to structure governance and prevent the abuse and concentration of power, including:
Article I, Section 8 – Grants Congress power to regulate the military.
Article I, Section 9 – Habeas Corpus: Protects against unlawful detention.
Article II, Section 2 – Establishes the President as Commander-in-Chief.
The Insurrection Act of 1807 – Permits domestic military deployment under strict conditions.
The First Amendment – Protects protest and dissent.
Impeachment and Judicial Review – Provide legal mechanisms to check executive overreach.
Given these constitutional provisions, what formal mechanisms—such as legal precedents, military oaths, internal policies, or codes of conduct—guide U.S. Armed Forces members in refusing unlawful or unconstitutional orders from political or executive leadership, including civilian authorities and superior officers acting under executive direction?
