With its forces stretched thin by the wars in Iraq and Afghanistan, the Army is looking to significantly expand the number of Reserve Officers' Training Corps programs on college campuses for the first time since the fall of the Berlin Wall in 1989, which led the Army to close more than 80 programs. At the University of Maryland-Baltimore County and other colleges that have applied for a program, the effort is being celebrated by cadets but criticized by faculty members and students who oppose the military's exclusion of openly gay service members. The Army's expansion effort stems from the Pentagon's request for the officer-training corps to produce 4,500 second lieutenants each year, a 15-percent increase over its annual quota four years ago. That target will rise to 5,350 in 2011. This year, ROTC produced 4,300 lieutenants, more than in 2007 but still short of its quota. That shortfall has the training corps looking for ways to produce more lieutenants, including adding 15 to 20 campus units to the 273 it already runs, according to Paul N. Kotakis, an Army spokesman. Naval ROTC, which includes the Marine Corps, is also looking to expand and has identified several universities where it may add programs.
