Well, clearly you took on a fair and non biased perspective. The fact of the matter is that Russian armies aren't hungry. I don't mean hungry in the sense of a need for sustenance, I mean hungry as in the drive to conquer and control.
The average Russian troop is underfed, underequipped, and underpaid. The only members of the Russian armed forces even remotely interested in waging war are the overpaid and overfed senior officers, who are so sure that Russia is the best, they figure any war effort they make is destined to succeed, contrary to historical perspective.
In addition, the lack of flexibility and disdain for innovation and improvisation in the higher ecehlons of the chain of command are detrimental to most campaigns outside of their homeland. However, this same lack of flexibility and rigid stubborness are excellent qualities for defending their homeland. With the weight of numbers and the motivation to defend their homes and families is on their side, the Russian military is a formidable force indeed.
