A question about the best shot of the Battalion Badge

[Jibba Jabba]

May I be the first to post to this section of the forum.

My question is.........if the badge with the crossed rifles with one star above is the Best Combined Shot of Cpl’s, L/Cpl’s & Privates in Regiment according to (Bosleys and according to the recent book published on trade/qualification/prize badges) why are these plain as day NCO's wearing the badge?

Am I to assume that one retains the badge on the dress uniform for as long as one serves in the regiment regardless of rank promotions?

Thank you for reading all help is very much appreciated.
