I second this, with the caveat that it is a difficult topic for the 1/72 to cover because discussions of cavalry tactics remain some of the most controversial in all of military history regardless of era to this day. 1/32 scale horses have similar issues, which is especially problematic for equine centric topics such as the American Western frontier in the late 1800s.
Just watched a new video today that detailed quite nicely how the whole theory of cavalrymen avoiding massed charges before Gustavus Adolphus at the beginning of the 30 Years' War is likely erroneous to some extent, and similar discussions about the successful practical implementation of lancer charges throughout Medieval times have also received some challenges. And do not even get me started on chariot warfare around 1500-300 BC, good god studies of that are a complete disaster (in my opinion, which is naturally not shared by all). Far too much information has been gleaned from the Illiad and the Odyssey, which is arguably equivalent to trying to reconstruct Medieval battlefield tactics by using a Lord of the Rings script.
