They call these fighting holes "ranger graves". Not because they are Rangers, but because these are the kind of combat graves a man would have been buried in during combat if extraction of the body was unable to be provided. Not to deep, but deep enough to protect the body for when they come back for it. Morbid, but true. Semper Fi.
its called a shellscrape... trust its the best place on earth after a full tiring day of training, and these marines are in a ops theatre, my experiences were only theatre simulations..... SALUTE to these elite citizens of the world !
