I re-read what I had posted and in hindsight I wasn't specific enough with my wording (inaccurate maybe a better way of putting it). What I was getting at was Russia's existing/remaining armour looks like it's been held back from front line work so it can be used for a new offensive in the new year once the ground is firmer and can support heavy units. When you look at the attrition rate manpower is still high whereas equipment loses have declined.
I understood your post, but this thread is fond of being overly touchy and aggressively uncharitable reading

As I said earlier, I think the drop in the involvement of armour is about the current conditions rather than any future planned offensive. I think we will see an offensive from the Russians in the new year, which may well involve this uninvolved armour, but I think it's better thought of a separate deployment rather than a tactical reserve of force saved from the current fighting.
