It's difficult to know where to start.
Are you really ex RN?
Is there any part of trying to rotate a crew of a warship every 30/60/90 days that is not utterly moronic?
Do you really think that rescue ops in the med is a tricky/tiring evolution?
A warship is not a foxhole. The med is not Iraq or Afghanistan or the Falklands. I think the RM/RN will cope with the stress from under their duvets in their comfy bunks.
Don't be so wet.
