DEPARTMENT OF MILITARY SCIENCE Professor Robert F. Zeidner, Colonel, U.S.A., Chairman Departmental Office, Military Science, Wasatch Hall The Department of Military Science (Army ROTC) offers two-year and four-year programs which provide instruction in general military science leading to a commission in the United States Army Reserve or for selected individuals a commission in the Regular Army. To enter the four-year program students must be: a. A male freshman student qualifying for entrance into WSC. b. A sophomore with credit for Junior ROTC or other military training. c. A sophomore pursuing a course requiring four more years to earn the bachelor's degree. The two-year program is for students who did not enroll as freshmen or sophomores but desire to compete for entrance in the advanced program. Selections for this course are made by the Professor of Military Science based on the results of qualifying examinations administered to the students by the department and the recommendations of a selection board responsible for interviewing the applicant following completion of the qualifying examinations. Students selected for the two-year program must 168 169
