What insignia do JROTC enlisted cadets wear on their gray beret?

The insignia that JROTC enlisted cadets wear on their gray beret is the ROTC insignia wreath. This particular insignia symbolizes their affiliation with the Reserve Officer Training Corps and is an important aspect of their uniform that signifies rank and branch within the JROTC program. Wearing this insignia establishes a connection to the values and traditions of military service, providing a visual representation of their commitment to the JROTC program and its principles.

The other choices provided do not match the requirements for the gray beret. Rank insignia, while essential in identifying the cadet's rank, is typically worn on the uniform itself rather than on the beret. The unit crest represents the specific JROTC unit the cadet belongs to, but it is not designated for wear on the gray beret. The cadet badge, which may denote certain achievements or qualifications, is also not the proper insignia for wear on the gray beret as per JROTC guidelines.
