By mid-1944 upwards of 600,000 soldiers of the Eastern Legions/Troops were assembled under the command of General Ernst-August Köstring, stemming mostly from the periphery of the Soviet empire; they consisted of non-Slavic Muslim minorities like the Turkestanis, the Volga Tatars, Northern Caucasians, and Azerbaijanis, as well as Georgians and Armenians.
"[11] Rolf-Dieter Müller puts the figures for the European Wehrmacht allies and volunteers who fought in the eastern campaign at approximately one-million men in total, which he claims gives substantial reason to "re-evaluate" the "military dimensions" of the overall collaboration.
[13] Müller also carefully reminds readers that on top of the co-opted aide of collaborators, millions of foreign laborers were forced to help provide the Nazis with the needed material resources to carry on the war far longer than otherwise possible without their toils.
