What act permitted the establishment of JROTC programs for branches other than the Army?

The JROTC Vitalization Act of 1964 is significant because it formally allowed for the establishment of Junior Reserve Officer Training Corps (JROTC) programs beyond just the Army, expanding the program to include other military branches such as the Navy, Air Force, and Marine Corps. This act recognized the value of promoting citizenship, leadership, and military discipline among high school students across various branches of the military, thereby enhancing the JROTC footprint in education.

The other acts listed primarily focused on different aspects of military or educational policy and did not specifically address the establishment or expansion of JROTC programs for multiple branches. The National Defense Act of 1916 primarily laid the groundwork for U.S. military training but did not lead to the inclusion of programs beyond the Army. The Elementary and Secondary Education Act relates to federal funding for education but does not pertain directly to military training programs. Finally, the Military Preparedness Act focuses on military readiness and not specifically on JROTC expansion.
