When you ENLIST in the armed forces, you swear an OATH, to die for your country if you have to. You don't sign up just because its a job and with good benefits. It is not a UNION JOB.
So please don't be offended when they put a weapon in your hand and ask you to defend the country.
Military service is generally a tool the rich use to keep the poor and middle class in line. Keeps protestors off the streets and the strict heirarchy assures abuses by officers against others occur unchallenged.
