Hi all I've been searching around the forums for ages and can't seem to find the answers to my questions, I'm currently filling out the application form (as the tittle suggests) and on the medical part it asks what your blood group is. I don't know so I phoned up my GP and he didn't know and he said that most people don't unless you've had a blood transfusion or similar. So can I just leave it blank? My other question is on the blue form where it says about your 1st and 2nd choices; do you have to put a second choice and how likely is it of getting your second choice? Or is just if I don't get the pass mark for my 1st choice of warfare officer? Any help would be appreciated!
