"The Captain of a MPA can sometimes be a position that is probably unique in any military setting, in that he can give orders to a vastly senior naval officer commanding another unit.
Dark Blue did not like that one bit, but how we enjoyed it."
Not very unique actually.
The Observer in a pinger, who may not even be the captain, has the same power when on scene cdr. SF do it all the time. (that is a bit of a guess, because who can tell their rank)
I have had the Captain of Culdrose as my P2 on many occasions.
I do however concur that the PWOs do not like it one bit. My observer made a PWO cry on the net. Ahh happy days........
