The Army Reserve Officers Training Corps unit remained unfilled this week when only 82 freshmen enrolled in the 100 new places offered at mid-term. Colonel Charles P. Summerall, Jr., professor of Military Science and Tactics, announced yesterday that the Military Department had accepted 96 out of the 120 freshmen who applied, but that 14 of those had either changed their minds about R.O.T.C. or were prevented from enrolling by difficulties in shifting their courses.

This small number of applicants from the Class of '54 is surprising in view of the widespread desire to enter the reserves last fall. With the Air Force unit limited by the small number of instructors and the Naval R.O.T.C.'s size set by law throughout the nation, the administration and students have asked for an expanded Army corps at the College.

Even with the latest increase, the R.O.T.C. unit compares unfavorably with those in other colleges, according to a Student Council report. Proportionally fewer Harvard men are in R.O.T.C. units than at other colleges, and of these, fewer Harvard men receive draft deferments because of the R.O.T.C.

About 530 Princeton undergraduates--one-sixth of the College--and 325 Yale men are now studying Military Science while Harvard has only 200. The Army and Air Force defer 175 Princeton freshmen while only 98 are deferred in Cambridge.

Not So Tough All Over

At an even smaller school, Knox College in Illinois, one-half of the 560 students receive deferments. All of the students in first and second year courses at the Illinois school get deferred; here only 58 percent receive deferments.

These other colleges all allow upperclassmen to enter the basic courses while Harvard does not. With the exception of those who just came into the unit, all men who have joined the R.O.T.C. in Cambridge have applied within the first week of their freshmen year.

The present R.O.T.C. also is weak in comparison with past Harvard units. President Lowell helped to pioneer the idea for such units, and in 1918 the local group was one of the first in the country and one of the largest.

In 1940, Army R.O.T.C. showed the way to expand in emergencies. The size at College jumped from 360 to 520 men then. Sophomores were allowed to join the corps too; in fact, they could do so until 1947. Military Science instruction was given in half courses in order that new enrollments might take place at mid-year.

660 Cadets

Today there are just 660 cadets in all three reserve groups at Harvard--256 in the Navy, 206 in the Air Force, and 198 in the Army. But the three units together make up the largest uniformed force at the College since the war. Most of the men are freshmen--more than a third of the total.

Last September the Navy alone turned down twice as many freshmen as it accepted. The field artillery battery would be three times its present size if it had not refused a mass of upperclassmen who tried to enter a year or more late. In the Air Force, the actual number accepted into Air Science 1, the freshman course, almost tripled over last year's total.

There are two kinds of R.O.T.C. students in the College today. One, the regular, is peculiar to the Navy, while contract students from the Air Force, the Army, and half of the Navy units.

Serve After Graduation

The regular students receive full scholarships to school from the Navy after competing in tough nation-wide exams. They are classified as midshipmen, much like those at Annapolis and must serve two years active duty in the Navy upon receiving their ensign's commissions at graduation.
