[5] In the years 1912–1913, he took part in the mobilization of the armed forces of the Austro-Hungarian Monarchy, introduced in connection with the Balkan Wars.

[13] From December 1918, he would serve in the Ukrainian Galician Army and was the active commander of the battle group "Khirov" of the 8th Sambir Brigade of the 3rd Corps of the UGA in the Polish-Ukrainian War.

[15] From 1924 in Vienna, Kravs was an activist of UGA veterans' societies, author of memoirs "For the Ukrainian cause."

However, according to Kyiv historian Andriy Rukkas, his figure is depicted incorrectly as his surname is distorted to Krevs.

The film also presents both false information about the military unit with which Kravs allegedly dealt in the Carpathians, and the absurdity about the incomprehensible solitary travels and meetings with Petliura.
