Parent here, Need Advice about daughter joining JROTC

Hello, I am the mom of a soon to be highschool junior daughter who wants to join JROTC. She is not very athletic, she takes Karate classes twice a week and that’s about the only physical activity she gets. She says she is interested in the challenging bootcamp like environment of JROTC. She is into art( professional level) and likes coding. She keeps to herself and has trouble socializing much IRL. Does it look like JROTC might be good for her especially because she is the one who is interested? Thank you for any insight.
