5 Points on Russia

1) Almost all the "advanced equipment" Russia has is untested and unproven, or fielded in such small numbers that any effect it might have in a war scenario is next to nil. Russia has been, for the better part of century, vastly overestimating the abilities of their equipment or resort to just making things up with no proof. 

2) Russia has a problem with logistics, all their advanced equipment doesn't count for anything if they can't reload or repair it. Problems with corruption and embezzlement are rampant. 

3) Russia has severe manpower problems, most of their troops are untrained conscripts who are only pressed into service for a year with extremely low morale. Professional soldiers don't reenlist and most units are manned at 40 to 60%. Again, advanced equipment doesn't count for s*** if your soldiers can't operate it, much less reload or repair it. They also have very few elite units that they shove in the limelight as much as possible to fool people into thinking they're competent (like the VDV and such) but most of their units aren't at that level.

4) The US Navy and Air Force dwarf their Russian counterparts in every measurable facet. We have 10 operational super carriers with 1 in reserve (Russia has 0), roughly 5 times the amount of planes in our Air Force (not counting our Navy or Marine jets), and better equipment and training for both. We simply outclass the Russians in every meaningful way, and that's totally discounting NATO or comparing our Army + Marine Corps to the Russian land forces. 

5) The Russian economy can not support war against NATO or the US. They consistently rank lower than countries like Italy or Canada in terms of GDP and their economy is in a recession at the moment. Sanctions and falling prices in oil have severely crippled them. 

My problem with this topic and every topic like this is people embellishing Russia's ability to make war while intentionally underestimating the US and NATOs proven capabilities. Most of it boils down to people being shills, willful ignorance, or people just regurgitating points from RT/Russian propaganda. 

Doesn't help that people cherry pick stuff that doesn't even compare, ie the US being bogged down "nation building" in places like Iraq or Afghanistan, which is nothing like a conventional war and also something that no conversational army that exists today is overly good at.
