What is a "Priority radio" ?

Question

Here is the sentense

"The captain told someone to get a priority rado message off to the naval commander at Willemstad and then asked, " How did you get on that island?"

Define Priority?

I don't get it =.=

Please and thank you!!!

Answer 1

It meant put every other message on hold and send that first.

Answer 2

That means no other messages go out before this one or a priority, that means , high rank or position, how did you get on the island ?, has to be answered before any other answer, that is the military way, hope it answered your question Lucy, good luck.
