What rank corresponds to O-6 in the Marine JROTC?

In the Marine Junior Reserve Officers' Training Corps (JROTC), the rank that corresponds to O-6, which is a Colonel in the regular military hierarchy, is Cadet Colonel (c/Col). This alignment reflects the rank structure utilized across various military branches, where the O-6 level in the officer ranks is equivalent to a Colonel.

Understanding the rank progression within JROTC is essential, as it mirrors the U.S. military hierarchy, allowing cadets to familiarize themselves with the ranks they may encounter in a professional military setting. Although other ranks such as Cadet Major, Cadet Captain, and Cadet Lieutenant Colonel exist, they correspond to lower and higher ranks than O-6, according to the established ranking system. Cadet Lieutenant Colonel (c/LtCol), for example, corresponds to O-5, and Cadet Major (c/Maj) corresponds to O-4, both of which are below the level of Cadet Colonel.
