I was quite concerned when I saw this. Those who were in Korea had spoken just what it was like to face an enemy that advanced like a flood tide. The machine-gun barrels melted but still they came on. Not all had weapons but they just picked up weapons from fallen comrades and carried on.
But, then something led me to have a Google round and I found this. Equally impressive in their drill. Drill is a result of cohesion. Cohesion is what leads to fighting discipline as described by the Korean veterans.
We are all still here so perhaps drill is not the be all and end all of military success. Better media now shows us just what fighting entails; for civilians just as for the actual participants.
Remember this when the 11th of November approaches and add something to the widow's mite.
