Concur, we were told diddly squat.
One trip I sustained a bad cut on my hand opening a tin of sausages. Fortunately we had tomato sauce so the sausages were OK.
I opened my FAK and strapped up the cut there and then.
I got a bollocking from the medics for opening my 'drug kit' and had to account for all the contents. Oddly the most powerful drugs were missing. 'Must have fallen out through the flare shut sir, very strong suck.'
I should have used the aircraft kit they said.
