Having been on a course at St Mawgan Survive Evade Resist Extract (SERE) recently I can tell you that they do now give you 10-15 minutes on what is in the med pack and what its for. Unfortunately, I was standing at the back freezing to death at the time and missed most of it. I Don't think Codene is in it any more (Also a "constipator"). I know an Eye ointment is contained in it that also doubles up as a good fire lighter.
