Congress has a plenary and exclusive power to determine the age at which a soldier or seaman shall be received, the compensation he shall be allowed and the service to which he shall be assigned. This power may be exerted to supersede parents' control of minor sons who are needed for military service. Where the statute which required the consent of parents for enlistment of a minor son did not permit such consent to be qualified, their attempt to impose a condition that the son carry war risk insurance for the benefit of his mother was not binding on the Government.[1240] Since the possession of government insurance payable to the person of his choice, is calculated to enhance the morale of the serviceman, Congress may permit him to designate any beneficiary he desires, irrespective of State law, and may exempt the proceeds from the claims of creditors.[1241] To safeguard the health and welfare of the armed forces, Congress may authorize the suppression of houses of ill fame in the vicinity of the places where such forces are stationed.[1242] TRIAL AND PUNISHMENT OF OFFENSES Under its power to make rules for the Government and regulation of the land and naval forces, Congress may provide for the trial and punishment of military and naval offenses in the manner practiced by civilized nations. This authority is independent of the judicial power conferred by article III.[1243] "Cases arising in the land and naval forces" are expressly excepted from the provision of the Fifth Amendment requiring presentment by a grand jury for capital or infamous and by implication they are also excepted from Amendment VI,[1244] which relates to the trial of criminal offenses. Also the Fifth Amendment's provision against double-jeopardy apparently does not apply to military courts.[1245] A statute which provided that offenses not specifically mentioned therein should be punished "according to the laws and customs of such cases at sea" was held sufficient to give a naval court-martial jurisdiction to try a seaman of the United States Navy for the unspecified offense of attempted desertion.[1246] In _habeas corpus_ proceedings a court can consider only whether the military tribunal had jurisdiction to act in the case under consideration.[1247] The acts of a court-martial, within the scope of its jurisdiction and duty, cannot be controlled or reviewed in the civil courts, by a writ of prohibition or otherwise.[1248] War Legislation THE REVOLUTIONARY WAR LEGISLATION
