Careers in the Military and Law Enforcement

The majority of law enforcement jobs are US government positions at the federal and state level and therefore are of interest to students interested in public service. The information below focuses on the maintenance of public order and enforcing the law. Please also refer to the “Government” resource page for more information about public service careers outside of military and physical law enforcement. 


Military Service

The five armed services are:

  • Army
  • Air Force
  • Navy
  • Marine Corps
  • Coast Guard

The first four services are part of the Department of Defense (DOD) The services draw their officer corps from ROTC programs at undergraduate institutions and their individual officer preparation undergraduate institutions. College graduates who do not complete ROTC during undergraduate can still apply to become an officer in the services through Officer Candidate School (OCS). More information can be found on the individual services websites.

Interested Wellesley students can enroll in ROTC programs offered at MIT through the College’s cross-registration program. Wellesley students may apply for scholarship aid from the Air Force and Army. Interested students should contact the appropriate service office at Massachusetts Institute of Technology, Cambridge, MA 02139, or call: Air Force, 617.253.4475; Army, 617.253.4471.
