Common Examples

President Orders Federal Training
Governor Linda Ortiz objects when the President directs an Army National Guard unit into federal service for joint exercises abroad. The land forces unit proceeds with the deployment because Congress authorized the call-up. The governor's request for an injunction fails.
Admiralty Jurisdiction Over Land Capture
During hostilities, Army land forces seize enemy goods stored in a coastal warehouse. The prize court accepts jurisdiction because the subject matter involves captures taken for the United States. The owners' motion to dismiss for lack of admiralty power is denied.

Executive Order Directs Steel Production
The President orders a domestic manufacturer to retool its lines for land forces equipment during a supply shortage. Congress had previously limited such directives without joint approval. The manufacturer obtains an injunction because the order exceeds executive authority.

Military Tribunal Tries Civilian
Land forces detain a civilian railroad dispatcher during a domestic uprising and try him before a military commission. Nearby civilian courts remain open. The conviction is reversed because a civilian cannot be subjected to military trial while regular courts function.

Commerce Power Limits Land Forces Use
Congress enacts a statute restricting federal regulation of local activities by land forces units. A challenge arises when the units attempt to enforce a federal firearms ban near a school. The restriction is upheld because the underlying conduct does not substantially affect interstate commerce.

Common questions
Frequently Asked
4
Does the term land forces include state National Guard units?+
Yes. When Congress calls state militias into federal service, they become part of the land forces under the President's command as Commander in Chief.
Supporting sources
Can the President deploy land forces for overseas training without a governor's consent?+
Yes. Once Congress authorizes the call-up, land forces units serve in federal service and the President may order training abroad regardless of state objections.
Supporting sources
May land forces try a civilian by military tribunal while civilian courts remain open?+
No. The Constitution requires that civilians be tried in Article III courts when those courts are functioning, even during domestic unrest involving land forces.
Supporting sources
Does a statute limiting presidential control over private industry affect land forces procurement?+
Yes. When Congress restricts direct executive direction of manufacturing for defense needs, an order compelling production for land forces falls to the lowest ebb of presidential power and is likely invalid.
