Military Justice for Reserve and National Guard Members

Reserve component members are subject to the UCMJ while on active duty, and while on inactive-duty training plus travel to and from the training site and the intervals between training periods (Article 2(a)(3)). Members of the Army and Air National Guard of the United States are covered by that inactive-duty provision “only when in Federal service.” When the Guard is not in federal service, its members answer to their state’s military code, and state courts-martial follow 32 U.S.C. §§ 326-327. A reservist who has returned to civilian status can be ordered back to active duty involuntarily for an Article 32 hearing, court-martial, or nonjudicial punishment, but only for an offense committed while on active duty or covered inactive-duty training (Article 2(d)).

When the UCMJ applies

Inactive-duty training. Article 2(a)(3) covers, “While on inactive-duty training and during any of the periods specified” below, members of a reserve component or the Space Force, and members of the Army National Guard of the United States or the Air National Guard of the United States “but only when in Federal service.” The covered periods are:

• travel to and from the inactive-duty training site, pursuant to orders or regulations;
• intervals between consecutive periods of inactive-duty training on the same day; and
• intervals between inactive-duty training on consecutive days.

Before the Military Justice Act of 2016, which took effect January 1, 2019, the paragraph covered only “Members of a reserve component while on inactive-duty training,” with the same Guard limitation (Cornell 2016 amendment note to § 802). The travel and interval periods were added then.

Active duty. A reservist on active duty is subject to the UCMJ like any other member on active duty; the general basis of court-martial jurisdiction is explained in the legal basis for court-martial jurisdiction.

Outside those periods. Conduct on a weekday at a civilian job, outside any covered period, is outside UCMJ jurisdiction for a reservist not on active duty, and is a matter for civilian authorities.

The National Guard: federal service or state status

The Guard limitation turns on whether the member is “in Federal service.” Whether a particular duty, such as a drill weekend or a federally funded mission, counts as federal service depends on the member’s orders and status; the source of funding is not the test written in Article 2. When the Guard is not in federal service:

• “there are general, special, and summary courts-martial constituted like similar courts of the Army and the Air Force”, with their jurisdiction, powers, forms, and procedures, but “Punishments shall be as provided by the laws of the respective States” (32 U.S.C. § 326);
• courts-martial “may be convened as provided by the laws of the respective States,” and the statute also lists federal and state officers who may convene them (32 U.S.C. § 327).

Model state code. The FY2003 National Defense Authorization Act (Pub. L. 107-314, § 512(e), December 2, 2002) directed the Secretary of Defense to prepare “a model State code of military justice and a model State manual for courts-martial to recommend to the States for use with respect to the National Guard not in Federal service” (note to 32 U.S.C. § 327). States are not required to adopt it; a Guard member’s state code is the law that applies in state status.

Recalling a reservist for discipline

When. A reserve component or Space Force member not on active duty who is the subject of proceedings under Article 15 or Article 30 “may be ordered to active duty involuntarily” for an Article 32 preliminary hearing, trial by court-martial, or nonjudicial punishment (Article 2(d)(1)).

Only for covered offenses. The recall is allowed only for an offense committed while the member was on active duty or on inactive-duty training, and for Guard members only when in federal service (Article 2(d)(2)).

Who orders it. Only “a person empowered to convene general courts-martial in a regular component” of the armed forces, under presidential regulations (Article 2(d)(3)-(4)).

Limit on punishment. Unless the Secretary concerned approved the order to active duty, the member “may not be sentenced to confinement” or be required to serve a liberty-restricting punishment outside a period of inactive-duty training or active duty (Article 2(d)(5)).

Speedy trial for recalled members

Entry on active duty under R.C.M. 204 is one of the events that can start the 120-day clock of R.C.M. 707(a). Article 10 is a separate protection for a person in pretrial arrest or confinement; see how speedy trial rights apply in the military justice system.

A Saturday night between drill days (hypothetical)

An Army Reserve soldier assaults another soldier in a hotel parking lot on the Saturday night between two drill days. That night falls within the intervals between inactive-duty training on consecutive days that Article 2(a)(3)(B) covers, so the soldier was subject to the UCMJ at the time. After the weekend, the soldier returns to civilian status; a general court-martial convening authority in a regular component may order the soldier to active duty for an Article 32 hearing and trial, and without Secretarial approval of that order the soldier could not be sentenced to confinement. If the same soldier were instead a Guard member on duty that was not federal service, the state’s military code, not the UCMJ, would govern.
