When any university, college, academy or other educational institution, incorporated under the laws of the State of Illinois, offers military science and instruction as a part of the courses of study regularly taught in that institution, and U. S. Department of Defense has detailed to that institution an officer from the U. S. army as professor of military science and tactics, the Governor of Illinois may, on the application of that university, college, academy or other educational institution, signed by the chancellor, president, superintendent, or other presiding officer, under the seal of that institution, declare that institution a post of the Illinois National Guard.
