Research Medieval Military tactics, namely Sappers. Underground fighting is NOT some new phenomenon.
Ask the Vietnam era tunnel rats. Or any veteran of the war on terror. They are the ones most likely designing those training exercises.
Also read up on the Battle of the Crater during the Civil War.
Underground fighting is as old as warfare.
