Dr. Emody. left front, is in the process of vaccinating soldiers of the 43rd Honved division of the Second Army. He is probably injecting them against typhus, a serious decimator of armies in the field since time immemorial.

Vaccinating Don Army Soldiers, 1942 (Hungary)

A unit of Hungarian machine gunners shown here manning a position by the Don. Magyar field artillery was effective here, but anti-tank guns were mainly small caliber and scarce,  tanks were hardly present in any number, and self-propelled artillery was not yet available. But they had good Mosin Nagant rifles.

Dr. Tamas Emody served as an army physician in Hungary and was assigned to the Second Army's 43rd division with the rank of lieutenant. He not only treated many wounded soldiers, and saved many lives, like at this field aid station above, but was also a prolific photographer, blessing us with a collection wartime photographs, partially shown here. He took his fateful dog with him to the front, seen in the next photo. After the Soviet breakthrough, he disappeared at the town of Nikolajewka on January 19, 1943, never to be located. RIP, good doctor, and thanks to your family for preserving your revealing photos.
