On paper, they have some key weapons such as new armour (tanks and IFV), electronic warfare and anti-air platforms at their disposal within their arsenal.
Yet regardless of they may spout, they're in limited capacity and untested; they may keeping them back to protect them or fear they'll fall to western intelligence.
Russia is still a materiel focused force, again regardless of what they say, so casualties of conscripted men won't bother them too much - they'll replace them.
Nor will they tell the Russian public the true casualty figures. However, can they afford to loose their new, costly equipment in ambushes? Perhaps not.
The Ukrainians are hitting logistics too. The MOD have reported again that the main columns are still bogged down a distance away from Kyiv.
