Chinese Military Parade at National day in 1999.
Like I said in previous post, submissive or obedient people are the best solders. They would follow the order to death. Trainabilty is depend on obedient personality and IQ. As we often consider most smart dogs like shetland sheep dogs, German shepherds ect are those breeds with best obedient quality.
Best soldiers is not equal to best army. A successful military force is combination of many different factors such as soldiers, generals, weapon technology, supplies ect. The most displined soldiers can not win battle without good weapon and supplies.
