Photo of a Red Army military medic with 4 cubars in his buttonholes

An original and rather rare picture in excellent condition. Size 81*111 mm. The reverse side is clean. The person depicted in this photo had not passed recertification by the time the photo was taken and the four squares in the buttonhole, according to the Order of the Revolutionary Military Council No. 1244 of October 2, 1924, which determined the table of the main combat positions and insignia, corresponded not to the rank, but to the position — K-6. For army ranks these are the commander of a separate company, the commander of a tank company, the assistant commander of a battalion and their equals. Guarantee of authenticity.
