But Congress can close the spigot (sadly, not likely).

Selected Reserve - Call To Active Duty

Section 12304 of 10 USC, authorizes the President, without a prior declaration of war or national emergency, to order not more than 200,000 members of the Selected Reserve to active duty involuntarily for any operational mission for not more than 270 days for purposes other than training under a Presidential Selected Reserve call-up. Up to 30,000 may be members of the Individual Ready Reserve. The emergency nature of a mobilization may require a rapid capability to assemble and deploy forces. Therefore, the Selected Reserve must be prepared to mobilize within 24 hours.

This category includes all Guard and Reserve personnel who have Selected Reserve agreements, whether trained or not, since they would all be subject to mobilization under the 200,000 recall authority. Those who have not yet completed required training would not be available for deployment on land outside the United States with their own unit or other units until completion of training. Active Guard or Reserve members, including those on full-time National Guard duty under 32USC 502(f), who are assigned to Guard or Reserve units will deploy with those units upon mobilization.

The Congress may terminate this call to active duty by a concurrent resolution of both Houses. All Selected Reservists called to active duty under this law are entitled to all reemployment rights and benefits provided to individuals under the Uniformed Services Employment and Reemployment Rights Act of 1994.
