From which site:

German grandfather, who is 89 years old. He went through the whole war without a single scratch, in captivity, which is typical, never was, served as a telephone operator. On the side of the Germans, of course. From the conversation with him it turns out that he has never heard or even suspected of such a calling as "URA!" He knows the word perfectly well. Because with such a scream, the Russians jumped into the barracks or went to attack. Another scream: "From now on, she is mother!" meant that now they would be attacked not only by infantry, but also by tanks.
