Add a year for cost increases

"The U.S. Navy has changed the terms of its ROTC (Reserve Officer Training Corps) program. Graduates now must serve five years on active duty, instead of four. The main reason for this increase is money. ROTC cadets have all their tuition costs covered by the navy, plus money for some living expenses and books. Some 150 universities have navy ROTC programs, which produces 1,100 ensigns (the lowest ranking naval officer) each year. The Naval Academy has always required five years of active duty from its graduates. The army and air force still only require four years active service from their ROTC graduates." Strategy Page
