Sir Alan West, First Sea Lord (these titles — truly mirth-making) in 2004 when Iran detained eight servicemen, comments on the current situation:

What training would the personnel have been given to help them in the event of capture?

These particular people would not be trained in counter-interrogation techniques because they are not expected to be captured. But I think our guidance to anyone in that position would be to say what they want you to say, let’s not be silly about it. Don’t tell them secrets, clearly, but if they tell you: ‘Say this’, well if that’s going to get you out, then do it. It means absolutely nothing, what they say, to be honest.

Rest here.
