Military Academies also train every student to be leaders, stress handling, character, endurance... whereas most university would not require leadership training and other positive but non-academic attributes.
That's great but those positive attributes can be had from a variety of other sources. As you say, Military training instils certain things - Regimentation, arrogance, the belief that everyone should share the same values, high regard for authority and maintaining the status quo. So sure, if you want a conformist, with a narrow view of the World, hire the Military.
Living near a Military town I have had my share of them. I remember one particularly earnest project manager. He was completely flummoxed by an unassuming bloke in the technical team, who arrived late every morning, sat on the loo for a couple hours reading printouts, before telling the rest of us how to clear the snag list and going home early. The PM spent most of his time barking at everyone for not working exactly how he would like them to, eventually disappeared up his own backside and had a nervous breakdown.
Since you think everyone is trying to shaft you, they very well may be! But you must look inward to figure out why you have such effect on people.
If you think how everyone might shaft you, you are a critical thinker. If you think everyone is trying to shaft you, that is paranoia :0
HR departments do not like any type of conflict. Engineers arguing the merits of competing technical solutions completely confuses them. I once got a very steely look from the HR rep when I answered a question, "Well, I wish I could solve all my problems just by talking to people but computers don't do compromise, in my experience."

My favourite question.
Q: "What frustrates you?"

Open ended questions in interviews is what frustrates me.
