Well, everything is right about obsolescence and very very poor command (that has always been the real problem in Italy... you can see still today if you know italian politics).
But please, be informed when you talk about Italian army in Russia ... try to imagine a small thousands Italian troops there in the winter, with "summer" clothes and shoes, without tank or halftracks ... do you really think other armies could stand Russian winter with summer equipment ? i do not know any famous army stood russian winter (from Napoleon to German Army with winter equipment) so put italian army there in the right context.
And again, there is no nationalist sentiment in Italy, we never had it, nor revisionism because everything connected with fascism is a bad souvenir and nobody is interested in that era in Italy
