It's "Ulla!" , Russian ура! Long live. It is equivalent to our army shouting "Go!" "kill!" Something like that. Be brave. Be brave. I think this kind of sound effect can be found on the internet. I think you might as well download a movie, find the charging scene, and then go to a better video store and ask them to help burn it.

There are many Soviet and Russian movies that have Ula effect. At the end of the storm gate, when Russian reinforcements charged, they shouted Ula. In the Battle of Moscow, the students of the infantry school also shouted Hula when they charged, which should be at the end of the third episode. I can't remember the other movies, so the landlord can find them himself slowly.
