Positions were you lead cadets look better than XO type positions IMO.
I wouldn't rely purely on JROTC if you are applying for ROTC, they look for a LOT more than that.
The XO position is one of the top positions in Army JROTC. It is part of the Top Staff in the JROTC. After the top staff comes the Company Commanders and leadership teams.
Duties and Responsibilities of the Battalion Command and Staff
