I did, and it was a mistake.
It is quite literally risking your life in order to establish and secure resource chains for the western oligarch class, for the privilege of going to school to be one of the oligarch's slightly higher paid underclass.
Despite all the cringe posters, there is no honor to be had in the modern military of the last 50 years. Like so much else, our military works in service to the interests of our owner class through our captured and well-bribed government. They've destabilized entire governments solely to improve commerce with the capitalist regime that replaces the last one.
One thing I am certain of, Constitutionality be damned, if the American citizenry ever does wise up and rise up against our owners, our military will be turned on us and kill as many citizens of this "society" as it takes to protect our beloved economy. 99% of soldiers will follow their paychecks and the promised safety of their families on secure bases and pull the trigger on us, too.
That's what happens when you let the growth/metastasis of your economy take precident over the good of your society aka its citizens as we did so very long ago. An economy is meant to be a lowly tool to better distribute goods and services for the benefit of the society it serves, just fyi.
