Ukrainian Army Has Better Morale and Fighting Ability that Russian One

Many people think that Ukraine has no chance of winning against Russia. Technically Russian Army is larger and has more artillery and sophisticated weapons.

However Ukrainian army has unique advantage Russia does not, better morale. Ukrainian soldiers on average are much more willing to fight for their country and win compared to their Russian counterparts. Spirit of Ukrainian Insurgent Army lives and men from Lviv valiantly fight in Donbas to prevent Russia from taking any more of Ukrainian land.

That is not absolute rule. Not all Ukrainian soldiers are motivated to fight. Some want out and their numbers will likely go up in total average in Ukrainian Army. Ukraine increases conscription efforts to supplement volunteer numbers. Conscripts naturally have much worse moral compared to volunteers.

However, on Russian side absolute majority does not want to fight. Most of Russian Army are conscripts and Russia is notorious for using cruel methods of dragging men into service against their will. Sure a few units are really motivated to fight, but they are clear minority in total numbers. 

Russian opposition to service is not driven by opposition to war, but rather due to poor living conditions in the military. So, you will meet a lot of people who cheer for Russian troops but will dodge service like a plague.

Quality of training and ability is also on Ukrainian side. Russian casualties at least twice as large as that of Ukraine and possibly many more. Russia was always secretive about its numbers, so we do not know how many of their million lost in battle dead and how many only wounded. Ukraine lost around 400 000 wounded and around 46 000 dead. 

Russia tapped into North Korean Army to plug the gaps in their own ranks, so we know they are suffering from troop shortages.

Overall Ukrainian Army, despite being outnumbered, performed a lot better than Russian one and managed to breach gap in numbers with their superior ability and morale. That proves that Russia is not a superpower of US level but rather a periphery state on Ukraine's level.
