Ok just making sure. I know that in the summer the Cadets can go to different schools Ranger...Airborne etc. That Cadet is obviously prior service.
Which means he'll be smarter than your average Butter bar graduate of Hudson High School for Boys (and girls). 
I didn't want to mention the ARCOM ribbon right under the CIB, but you're right--he's obviously prior service. And when he finally gets his butter bar, he'll command a fair amount more respect (I added this for those who would see this, who haven't served in the armed forces) than, say, I did, straight out of college (but I knew to listen to my NCOs).
