on 1 jul 43 the rus tank force out numbered the ger by 4x yet during the entire year the rus only out produced the ger in oil by double. on the same date the rus arty tubes out numbered the ger by 4x yet it was the ger shell production that out numbered the rus. the ger would fire more than 4x as many arty shells per tube as the russians. the russians were so short of arty shells that 1 in 3 shells were fired directly with higer loss rates amoust the crew and gun.
the rus were so concered with producing large numbers of equipment to keep up with their higher losses they could not keep up with proding large numbers of supply items. they also over produced in the equipment department thinking that more was allows better.
