As this photo shows, sometimes Einsatzgruppen victims were made to strip, so that their clothing and personal effects could be re-used. Photo Description: Jewish women from the Mizocz Ghetto in the Ukraine, which held roughly 1,700 Jews. Some are holding infants as they are forced to wait in a line before their execution by Germans and Ukrainian collaborators.

Einsatzgruppen

I believe someone was referring to this photo earlier today (maybe on another thread).  Found at http://www.aeronautics.ru/archive/wwii/baltic_nazis/latvia/contact.htm
Description:  Such was the scale of the German slaughter in Russia that the German command was hard-pressed to find the most efficient form of extermination, particularly with respect to the Jews. Some German commanders disliked the inhumanity of hanging. The preferred method of the Einsatzgruppen, the SS extermination squads, was to round up all Jews and shoot them out of hand. Here, a "standard" execution is watched by a youth (centre), a member of the Nazi youth labour organization. (Source: "The Eastern Front in Photographs", by John Erickson)

Photo Description: A German policeman shoots individual Jewish women who remain alive in the ravine after the mass execution. (1942)
