I thought so. Did I miss something? I thought the point of the story is that this guy was an American Soldier who was injured in a car wreck and is now receiving disability pay because he is too disabled to be an American Soldier. I think the author was trying to show the irony of this fellow being too disabled to serve in our military, but still physically able to fight for others. It proves this guy doesn’t need disability pay from the American taxpayer. What did you read?
I guess you can say you missed something about the US military, as well as other aspects of US life - like education - already taken over by islam to the point of you being guests, unwelcome at that, in your own country.
