The source of ulla
Wula was introduced by Russians from other cultures. There are many theories about its origin.
One saying comes from "Tatar". Tatars mentioned by the ancients are not Tatars in Russia today, but refer to many tribes of Mongols. Professor Jack Weatherford, an American national historian, pointed out that the word "Wula" was originally a declaration that the Mongolian army spread to many places in Europe and Asia in the13rd century. The ancient Russians who were oppressed by the Mongols for hundreds of years inherited the conquest declaration of that year: "Wula".
Another view is that "Wula" was originally a German marching slogan, which originated from the word "Wula" in Highland German. The prototype of "Hurra" is "Hurren", which means "fast marching". After the introduction of the Russians, it extended to victory. Germany has long been the object of Russian military study in history, so it is very possible for Russia to introduce German military slogans.
