I could understand if we were even in High School not doing any leg work but, we all know how to use the Internet ad so does Hitech.
Did a search in Russian and here is a "translation" that shows up at all P-63 Russia history pages in one form or another.
During a short campaign in the Far East, the Kingcobras were used to escort bombers and reconnaissance aircraft, cover troops and ships from the air, attack and bombard the Japanese positions. On the second day of the attack, 40 IL-4s, under cover of 50 R-63, bombed the Chuzhou fortified area, from where the Japanese bombarded the Soviet city of Iman. Parts of the 190th and 245th divisions supported the advancing Soviet and Mongolian forces, acting mainly as fighter-bombers and attack aircraft, also covering transport planes delivering fuel to advanced tank and mechanized units. The bombs were taken by the Soviet, FAB-100, for which several bombers reworked. Underwing large-caliber machine guns, attached to some of the P-63 series, were usually not installed, the 888th and 410th regiments attacked Japanese bases on the Kuril Islands, and then ensured the landing of assault forces on them.
Japanese aviation practically did not seriously oppose the advancing Soviet Army, therefore, it was not possible to check the quality of the Kingcobra in air battles. The only successful battle on the R-63 was conducted by Junior Lieutenant I. F. Miroshnichenko from the 17th IAP (190th IAD). On August 15, he and his leader, Hero of the Soviet Union, Sirotin, attacked two Japanese fighters who attacked transport aircraft approaching the landing in the Vaneemiao area. One Japanese man was shot down, another disappeared, having gone on a low-level flight among the hills. The type of Japanese cars in different documents is indicated differently. And as “I-97” (i.e. Nakajima Ki. 27), and as “Oscar” (according to the American code, Ki.43 was so designated). But he and the other were long-obsolete aircraft, so that the outcome of the battle was actually predetermined from the very beginning.
