Actually a GED or a High school diploma is required to enlist in the United States Army. Not only that, but our officer corps are required to have a BA to be an officer and the majority of our senor NCO's have either a BA or a Masters (promotions amongst senor NCO's is incredibly tough)
Even if you were right, our bunch of High school drop outs still outclass and outperform any other military force in the world, what does that say about your third rate country's military?
