SMP Cadet wearing Blue Cord?

You can wear EITHER your military awards and decorations OR your cadet awards and decorations. They can not be combined. If you wear your blue cord, then you must wear the awards and decorations as you would if you were not a cadet. That means you can not wear any cadet ribbons or other awards. Any infantryman I know would choose to wear the blue cord with 3 ribbons rather than a hundred cadet ribbons. I'm sure this is covered in some cadet command regulation, but I don't have the reference handy. Hope this answers your question, though.

This has been going on since the Infantry cords inception, the rule of thumb is the regs. Look at your Line and paragraph number on the UMR. in addition your commander right or wrong can authorize you to wear your cord if you meet all the requirements, remember your disks go with the cord. I have seen other infantrymen that shouldn't be wearing our cord all the time doing mental gymnastics to justify it. My Primary MOS has been Infantry for a long time and I have been assigned to !!B slots but unless I met the requirements above I was not authorized to wear my cord or disk. I am not against wearing it but sometimes the inconvenient truth is the Reg say no unless we fall under the provisions. If enough Infantrymen got together and requested a change through the available system to address change, maybe it would be changed but up to the 2015 AR 670-1 its still a no go.

(5) When worn.

(a) During the period of assignment to an infantry regiment, brigade, separate infantry battalion, infantry company (including the headquarters and headquarters company of an infantry division), infantry platoon, or infantry TDA unit. In addition, infantrymen assigned to infantry sections or squads within units other than infantry units may wear the cord when authorized by battalion or higher-level commanders.

(b) During the period assigned for duty as an Army recruiter or advisor, ROTC instructor, or member of the staff and faculty of the U.S. Military Academy, as long as the individual retains an infantry PMOS or specialty.

(c) During the period of assignment at brigade- or lower-level BT or advance individual training units, or in OSUT infantry units, as long as individual retains an infantry PMOS or specialty.

(d) Infantry OSUT and Infantry Officer Basic Course graduates may wear the cord en route to their initial follow-on
infantry assignment.

(e) Soldiers en route from an assignment where wear of the shoulder cord was authorized are permitted to wear the shoulder cord if they are pending reassignment to another organization authorized wear of the cord, or when assigned to a separation point for discharge purposes.

I would start with CCR 670-1. Then AR 670-1.

From my interpretation and in combination with the two referenced regulations, the answer to your question is no. Check chapter 3 of CCR 670-1.

What rank and branch insignia do you wear as an SMP member? Is it Enlisted Rank, Cadet Rank, or Officer Rank? I would venture that you are wearing Cadet Rank insignia, so the answer is probably no.
