Article I, Section 8, Clause 12a

Congress raises and supports armies

Current text
To raise and support Armies,

What it means

Congress may raise and support armies. The text supplies national authority to create and sustain land forces, rather than depending exclusively on separate state military contributions.

Historical setting

Federalist 41 acknowledged the danger of standing armies while defending sufficient means of national defense. The founders did not resolve the danger by prohibiting a peacetime army altogether.

What it does

The President’s command role presupposes forces whose legal organization and support Congress can provide. The following appropriations limit and other congressional powers prevent military capacity from becoming solely an executive matter.

Debate & interpretation

The fundamental tradeoff is that effective defense may require institutions capable of coercion at home as well as abroad. Constitutional restraints therefore address authorization, money, and command instead of assuming military virtue alone will protect liberty.

A common misreading

The Constitution does not categorically prohibit maintaining a standing army in peacetime.

Think it through

How can a republic maintain forces strong enough to defend it without making them independent of civilian government?
