Not sure if ive missed this being raised in the previous 180+ pages but one of the challenges that Russia might be facing is its approach to its Army. Historically they have relied on their warrant and other junior officers as the backbone as opposed to NCOs in western armies. They have also previously relied heavily on short term conscriptions as opposed to professional soldiers. While this has changed over the last 20 years they still struggle to attract and retain long term experienced soldiers. The defence budget in Russia has also been reduced in recent years when viewed against the size of their army, this impacts on pay and training quite significantly.
