I think that the first one is between British Grenadiers vs. Irish Rebels from the rebellion in 1798. For the second one, I'm guessing its NVA or Vietnam People's Army vs. the ROK Army. Third, is obvious, Manchu Imperial Brigade vs. Praetorian Guard. Fourth is Marine Raiders vs. a division in the Red Army
