Waking up before dawn with the Sargent Instructor banging a trashcan lid with a baton yelling “Drop your cocks and grab your socks! It's another Marine Corps day!”
Problematic sleep due to the positioning of our OCS barracks BETWEEN the major AMTRAC north-south line that passes through Quantico on the one side and the runway of the Quantico Marine Corps Air Station on the other side!
It is best to be in the absolute peak of physical conditioning possible BEFORE arriving at Quantico.
Best of luck to your son. They will apply maximum sustained stress to try to get him to resign or fail physically for his own good and the good of the Corps, if he can't take it.
Appreciate that -He is already a Marine. And, he is completely dedicated to staying in top physical shape.
