As a surgeon, I was lucky to do 2 humanitarian trips. One to Jamaica, which was a waste of time because the senior surgeons did not really want me to train anyone below them, and also because of the poor prep. I basically took them some outdated equipment, and was able to do a couple of cases, but nothing like the medical side which saw hundreds and hundreds of patients.
My second one was the most fullfilling. It was permissive tdy that was approved at surgeon general command level, because I got a letter from them. Of course, it was all civilian planned. I went to Nicaragua, and taught surgeons how to do lap choles for 7 days, 6 am to 6 PM, as many cases as we could do. They had already done a didactic course set up by the organization under whom I went.
Of course, to end on a good note, while I was there, some a**hole from central command called me up in this remote village, where there is only one phone for the entire hospital, to tell me I was violating territorry, and had not sought approval from central command to be in country. Since I had over 50K worth of equipment, and people to teach, I told him in my officer like manner to go to hell, and do the paperwork wiht my base who had approved my coming there. Eventually, the health minister called the embassy, and I got no more phone calls. When I got back, I wrote up a debreif explaining my actions and my service, and everything was OK till about 6 months later I was accused of not following protocol when I got in trouble for parking in the patient parking lot, on safety day, when there are NO SCHEDULED PATIENTS ANYWHERE OTHER THAN EMERGENCIES. That is only one of the reasons I hated the military so bad, and still cannot respect stupidity. The one freaking day when the lot is not used you can get in trouble for using it. I guess its that stupidity that got me out anyways, as I jaywalked my way to freedom. The military sucks so bad, it still burns me up.
But digressing, in today's climate, the most humanitarian you will get, is to treat Iraqi nationals that have got blown up
