The medal booklet doesn't specify his rank. The Medal for Courage entry on Podvig Naroda, which may well be his, lists him as a Private. Had he been an officer, there would have been options to get his photo, but there are no photos of enlisted personnel in the archives.
The division that started out as the 10th NKVD Rifle Division is the division you're looking for (this was actually the third 181st Rifle Division to be formed during the war). It was awarded the Orders of Lenin, Red Banner, Suvorov, and Kutuzov. In the time frame we're looking at (early July 1943) the division was deployed in the northwest section of the Kursk salient (under the 65th Army), although the 181st didn't see any combat in the first stage of the battle of Kursk. On July 13 the division was placed under the neighboring 70th Army and it joined in the offensive on July 15. The action Gunner 1 described took place that day.
