Step-by-step explanation:
The Junior Reserve Officers' Training Corps (JROTC) was created by Congress under the National Defense Act of 1916. This program was established to provide military training to high school students and to instill in them a sense of personal honor, discipline, and other values beneficial to the service of their country. The Department of Defense, which includes the Army, Navy, and Air Force, was later formed from the previous individual military departments under reorganization plans initiated by the National Security Act of 1947 and fully established in 1949.
