The Swiss military criminal code contains additional prohibitions under the general title of "treason", which also apply to civilians, or which in times of war civilians are also (or may by executive decision be made) subject to. These include espionage or transmission of secrets to a foreign power (art. 86); sabotage (art. 86a); "military treason", i.e., the disruption of activities of military significance (art. 87); acting as a franc-tireur (art. 88); disruption of military action by disseminating untrue information (art. 89); military service against Switzerland by Swiss nationals (art. 90); or giving aid to the enemy (art. 91). The penalties for these crimes vary, but include life imprisonment in some cases.
