As a veteran, I dislike veterans that walk around with a sense of entitlement.
US military personnel get paid well, get good benefits and are generally treated well, both while in service and when leaving service. The job can really suck sometimes and it can be very hard, but no one tells you it will be easy. The suckiness and difficulty also makes it one of the best jobs in the world because you have purpose and buddies that are right there with you. I'm grateful for my time and no one needs to thank me for doing it.

I'm not a veteran. I appreciate those that choose that line of work. But it is a choice just like any job. All volunteer force just means you choose to go into that line of work. 

Unless you live outside of the US, then many countries have compulsory service. I wonder if veterans from those countries have the same attitudes.
