Which military branch is the JROTC program most commonly associated with?

The JROTC program is most commonly associated with the United States Army because it was established by the Army in 1916 as part of the National Defense Act. The primary goal of JROTC is to instill values of citizenship, service to the community, and personal responsibility among high school students through military-style training and education. While there are also JROTC programs affiliated with other branches, such as the Navy, Air Force, and Marines, the Army's program is the most widely recognized and has the longest history. This foundational association has developed a strong identity related to Army values and leadership principles within the JROTC framework, making it the most prevalent branch linked with the program.
