Also: To whomever made the comment about NTPs not putting up with training because it'd be pointless, I disagree. If I joined the military, I could accept the training for a shit-ton of training, the basics of which is that the training is used to protect my life. That's a pretty good fucking motivator.
What about the training to charge a machine gun nest against your better judgment because your superior officer thinks its a good idea?
Also, whoever thinks being an INFP in the military is a good idea should watch the first half of Full Metal Jacket.
Listen to me, baby, you got to understand, you're old enough to learn the makings of a man.
Oh whatever, I'm a female entp and did just fine in the military. granted, some of my reviews were not very nice, but whatever I always got the job done.
If anything, I learned you can't tell who's going to be able to really take it outside of training. Some of the biggest, strongest, toughest guys who rocked out during training, fell apart in the field.
I think it has less to do with type/gender and more to do with mental fortitude. You can prepare and train all you want and some of that may weed out a few people who would not make it in the field, but ultimately until you get there you really don't know who you're working with.
