rabidrabit , do you think Russia is going to be able to sustain this war?
That is a complicated conversation once you dig into it. In a nutshell, They are burning resources much faster than they can replace them however, they can continue doing so for at least a few more months. If the Ukes can't build up mobile forces to conduct combined arms pushes they run the risk of continuing to be dragged out in ww1 style trench warfare where Russia has some advantages. That is why they are asking for more tanks and IFV's. They don't want to get stuck mutually grinding away lives.
There are many facets to the conversation so ask away any I'll share my opinions on them.
