In the back of the article he talks about the imaginative commanders of the 3RD ACR at Talafar and how they fought as Dragoons "corralled their horses" motor pooled their tanks and fought as dismounted infantry. He also mentions in the back a question about why were some mechanized units able to fight so well why others could not. It short it is the Cavalry Dragoon doctirne (mounted Infantry) is what he is talking about. I will comment more on this later at my day job.
