Posse comitatus governs the use of AF personnel in which location?

The Posse Comitatus Act primarily restricts the use of federal military personnel in domestic law enforcement roles. This includes activities such as conducting searches, seizures, arrests, or other actions that involve the enforcement of civil laws within the United States. Therefore, when considering the influence of Posse Comitatus, the correct focus is on its applicability within the continental United States (CONUS).

This legal framework emphasizes that military forces should remain separate from civilian law enforcement unless specifically authorized by law or during a national emergency, emphasizing the jurisdictional boundaries that protect civil liberties. As a result, the guidelines shaped by the Posse Comitatus Act are particularly significant when AF personnel are operating domestically, as they cannot engage in law enforcement activities, preserving the constitutional balance between military and civilian power.

The other options do not align with the limitations imposed by Posse Comitatus. The act does not apply internationally or in locations outside CONUS in the same way, as military forces can operate in a different capacity abroad. Additionally, while military zones do have specific rules, they fall outside the primary concern of Posse Comitatus, which is focused mainly on domestic law enforcement issues.
