My t thoughts go towards how did the RIB crew(s) come to find themselves in that predicament to begin with.
It is plain....they did not have the back-up support needed to ensure their safety.
Considering the situation, past conduct by the Iranians....going down with the ship with guns ablaze certainly was not the ending this situation demanded or would be be expected.
I did like the comment in the Report about "overly complex SOP's".
For the Captain....taking a hard line begins at 10 Downing Street and not on the Deck of a RIB in contested waters with a small boat crew with no backup.
