If you are current and have recently served in a medical role then it should all be fine.
If you've done BATLS before then you will need to wind your neck in, PHTLS is handy with needles but they still shy away from knives.
Take a hint from the previous post, you get the world and his dog on PHTLS so it's easy for some, rock hard for others, just depends on where you're starting from
trumpton shouldn't be doing PHTLS , but it's ok they have their own faculty ... I've seen IHCD techs and the better 50 % of VAS crews pass the course with little sweat - and that's mainly been over some of the harder theory stuff, Health professionals should have no problem with the theory asnd as some of the skills labs are really just for shits and giggles ...
