The Constitution's Military Provisions: What And Where?

The US Constitution outlines the power of Congress to raise and support armies and a navy, to suppress insurrections, and repel invasion, among other military-related governmental roles. Article I, Section 8 of the Constitution enumerates Congress's powers, including the ability to declare war and raise armies. The Framers of the Constitution gave these powers to Congress to act as a check on the president's power as commander-in-chief of the military. The Constitution also divides power over the military between Congress and the president, with the Posse Comitatus Act barring federal troops from participating in civilian law enforcement without express authorization.

Military personnel swear allegiance to the Constitution, not the President

The US Constitution is central to the country's military, with military personnel swearing allegiance to the Constitution rather than the President. This oath is taken by all military members, including the President, who is the Commander-in-Chief of the Armed Forces.

The Constitution outlines the powers granted to the federal government concerning the military, with Article I, Section 8, Clause 12, known as the Army Clause, stating: "The Congress shall have Power To...raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years." This clause highlights the checks and balances in place regarding military power, with the President commanding the army and Congress financing it through short-term legislation.

The unique, separate status of the military is emphasized, with the Court recognizing that the military is a "specialized society separate from civilian society." The Court has upheld the validity of military post regulations, banning partisan political activities to maintain military neutrality and troop morale.

Military personnel swear an oath to defend the Constitution from all enemies, foreign and domestic. This allegiance is supreme, while obedience to the President is conditional, based on lawful orders. There have been instances where military members have spoken out or taken a stand against unlawful or immoral orders, highlighting the importance they place on their allegiance to the Constitution.

The Constitution also addresses conscription and compulsory military service, with historical examples of debates and legislation surrounding this topic. The Supreme Court has weighed in on the constitutionality of conscription, providing interpretations of how it aligns with the Constitution.

Conscription and compulsory military service

Conscription, or compulsory military service, has a long history in the United States, dating back to the colonial era. During this period, colonial militia laws required able-bodied, non-enslaved males to enrol in the militia, undergo military training, and serve in times of war or emergency. This early form of conscription involved selective drafts of militiamen for specific campaigns.

The Continental Congress in 1778 recommended that the states draft men from their militias for one year's service in the Continental Army, marking the first national conscription. However, this effort was irregularly applied and failed to adequately fill the Continental ranks. During the American Revolutionary War, the states sometimes drafted men for militia duty or to fill state Continental Army units, but the central government lacked the authority to conscript.

The constitutions adopted during the Revolutionary War by at least nine of the states sanctioned compulsory military service. Towards the end of the War of 1812, James Monroe, then Secretary of War, proposed conscription for the army. However, opposition arose, and peace was achieved before the proposal could be enacted. In 1863, a compulsory draft law was adopted and implemented without facing legal challenges in federal courts.

The Supreme Court's rulings have played a significant role in shaping conscription policies. In 1918, the Court upheld the constitutionality of the World War I draft in the Selective Draft Law Cases, rejecting arguments based on states' rights, the 13th Amendment, and other constitutional provisions. The Court's decision emphasised the power of Congress to declare war and raise and support armies, including the authority to mandate conscription.

While the Supreme Court has declined to formally rule on the "peacetime" draft, its opinions suggest that conscription is constitutionally valid. The Court has affirmed Congress's broad constitutional power to classify and conscript manpower for military service. Additionally, the Court has upheld the constitutionality of statutes prohibiting the destruction of selective service registration certificates.

Congress can legislate for the military with greater breadth and flexibility

The US Constitution grants Congress significant powers in relation to the military, allowing it to legislate with considerable breadth and flexibility. This is underpinned by the recognition that the military is a "specialized society separate from civilian society", governed by distinct rules and discipline.

Article I, Section 8, Clause 12, also known as the Army Clause, explicitly states that "The Congress shall have Power To... raise and support Armies". This clause limits the appropriation of money for this purpose to a maximum of two years, providing a check on the maintenance of a standing army during peacetime.

Congress's authority over the military also extends to conscription and selective service. While compulsory military service has been challenged on constitutional grounds, the Supreme Court has upheld its validity, dismissing objections based on the Thirteenth Amendment. The Court has deferred to Congress's judgment on matters such as the roles of sexes in combat and military mobilization.

Additionally, Congress has the power to regulate military affairs, including the enforcement of rules and discipline within the military community. This includes the validity of military post regulations, such as banning partisan political speeches and demonstrations without prior approval, to maintain troop morale and neutrality.

The unique nature of the military grants Congress the flexibility to adapt constitutional protections to the specific context of military society. This is exemplified by the oath taken by military personnel, swearing allegiance to the Constitution and upholding their duties, even when faced with unlawful orders.

The deployment of the military for law enforcement

However, there are exceptions and loopholes within the Posse Comitatus Act that allow for the use of the military in certain law enforcement capacities. One significant exception is the Insurrection Act, which grants the President broad authority to deploy the military to suppress insurrections, enforce federal law, and protect civil rights within a state. This Act has been invoked in various instances, such as during the 1992 Los Angeles riots and in 2020 when President Trump deployed the National Guard to police protests in Washington, D.C.

Additionally, the Posse Comitatus Act does not apply to the Army National Guard or Air National Guard when acting under state authority within their home state or an adjacent state, if invited by the governor. This exception allows for the use of military personnel in law enforcement capacities, particularly in states where the National Guard is involved in homeland security or disaster response roles.

Historically, the use of federal troops in domestic law enforcement has been rare, especially in the past half-century. The U.S. Constitution limits military involvement in civilian affairs, and Americans generally view the use of the military as a domestic police force as a threat to democracy and personal liberty. However, there have been instances where military assistance was provided without the explicit request or authorization of state or federal authorities, such as in the case of the 2009 shooting spree in Samson, Alabama.

The question of the military's role in law enforcement is a delicate balance between maintaining order and respecting constitutional liberties. While the Posse Comitatus Act and related laws provide a framework for limiting military involvement, exceptions and ambiguities within these laws have led to concerns about the potential for overreach. As a result, there is ongoing discussion and efforts to reform and strengthen the laws governing the deployment of the military for law enforcement purposes in the United States.

The President can command the army, but Congress finances it

The US Constitution outlines the powers of the President and Congress in relation to the military. While the President is the Commander-in-Chief of the armed forces and can command the army, the power to raise and maintain armed forces lies with Congress, which also holds the purse strings. This division of powers between the executive and legislative branches is a key feature of the US political system and is intended to provide checks and balances.

The Constitution, specifically Article I, Section 8, Clause 12, known as the Army Clause, states: "The Congress shall have Power To... raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years." This clause gives Congress the authority to establish and fund the military, but with the limitation that funding must be approved regularly to ensure continued oversight.

The Constitutional Convention of 1787 in Philadelphia recognised the need for checks on a standing army, and thus granted the President the authority to command the military while giving Congress the power to finance it. This balance of powers ensures that the military is governed by civilian authorities and subject to democratic control.

Congress's power over the military is further demonstrated by its ability to legislate for the military separately from civilian society. This includes matters such as conscription, which has historically been upheld by the courts as a valid exercise of congressional power. Additionally, Congress has the authority to enact post regulations for the military, such as banning partisan political activities on military bases.

While the President is the Commander-in-Chief, their commands are subject to constitutional limitations. Military personnel swear allegiance to the Constitution, not the President, and are expected to disobey unlawful orders. This allegiance to the Constitution ensures that the military remains accountable to the principles and values enshrined in the nation's founding document.
