Hm this is a good thread. I keep a first aid kit in the car, but don't take one airsofting. If I was going on a milsim I may take a simple personal kit, but the sites I play at all the marshalls are first aid trained and each carry first aid kits on their person all the time, so you're never more than 20 seconds from someone with the proper training and equipment to treat you before the ambo arrives. The first aid kit we keep in the car is fairly complete, and I have some extras in as well such as inflatable splints and the like. Found out the hard way that there's no suitable bandage in it to make a sling which was a bit crap I was out with my folks and my mum fell and snapped her arm in three places. Used to have Oramorph too but it expired last year so it was thrown out, and while my last doctor who'd been our family GP for 6 years or so was on board with "just in case" prescriptions from when we used to go on 2 and 3 day offroading and camping trips, since we moved, the new doctor is miserable as sin and won't touch anything like that with a barge pole. Anaesthetic in the first aid kit is limited to OTC lidocaine.
