The Protocol created by the students is unique to them and does not matter as much as them realizing one is needed. I thought about personal experience talking on CB's and other radios. There is always a speak and respond format that is needed to be efficient. "Base to DM4, what is your 20"
"DM4 to base, 1700 block of First"
"DM4 proceed to Golden Palace, order Bravo 6-2-1-1-niner"
"Copy that Bravo 6-2-1-1-niner, 10-4"
