That does bring up a good point.
I see this a lot in vids for naval and submarine games:
"Helm, steer course 052"
"Helm, aye"
You have to understand just how P.O.'d an OOD would have to be with a Helmsman to give that order.
It
is a valid order, but you would never give it. It would be like saying "steer course 302.779835".
Carry on..
