EA-6B1,
There were a lot of people that didn't make it. I have no idea of exact numbers but I want to say that the majority were DORs or got dropped. DOR means Drop On Request. Basically, they quit the legal way instead of just walking out in the night like a few people did. There were a good amount of people who left with injuries as well. I don't think that one heavily outweighed the other but, like I said, I have no idea about numbers.
As for pictures of me, there are a few. The most noticable is the 11-mile hump. I'm the one carrying the guidon.
As for the reasons the candidates were dropped, any failing categories (academics, physical, leadership) and a lack of impressing your platoon staff. Physical is a quick one to get dropped on. If you suck on the physical tests, the platoon staff will be looking to send you home. None of it is very difficult in itself if one just applies themself enough.
