In the book review section, I saw a reader asking if Japanese horses can wear vests? My answer is: The Takeda family's red cavalry can wear vests, why can't the Uesugi family's cavalry?

Takeda Red Reserve - A descendant unit trained by Takeda Shingen. The best horses are selected, and then the soldiers are repeatedly selected to be ten elites, trained by the devil, dressed in heavy and full, long bayonet guns, and even the horses are covered with a full set of vests, and the defense and lethality are extremely high. The full set of armor and vest worn in battle is red, so it is called "Red Reserve". It has terrifying charging lethality.

This paragraph was seen on Du Niang. Although Japanese horses are not as good as the horses of the Celestial Empire and Europa, their combat ability can be regarded as one of the best in the island nation. Otherwise, Tokugawa Ieyasu would not have made great efforts to recruit the remnants of the Takeda family to form Ii Akabi.

The vest of a Japanese horse is not an iron armor, so it is enough to say that the defense can defend against the arrows of the island country that are not very lethal.
