Shield and braid are interchangeable words that basically refer to the same thing. Similar to your coax braid that covers its center conductor, with mic wiring it’s the braided or shielded wire that covers the audio wire.

thank you for the reply .....does the shield/braid always cover the audio wire ?

I would never say "always", but as far as CB radio mic wiring is concerned, yes. Some extremely low impedance or carbon mics that are found on some old commercial radios (police, fire etc) will be absent of any cord shielding. Those will be a mismatch for CB radio purposes anyway. As long as you stay with mics that are meant for CB, you should be fine.
