As per Dimitri Rogozin the real push is yet to begin . There are about 600 tanks of Ukraine around Orekhov , and there are more numbers of infantry fighting vehicles positioned . And this morning Ukraine with massive artillery strikes managed to occupy several positions of Russian troops in Orekhov- Tokmak direction . So there is more action to come . And if only Ukriane had better aviation support , things cld have been even more favourable to them . (info from From Russian sources )
Not sure about those numbers.
The current official Pentagon released estimate is 250+ tanks and 800+ IFVs and APCs in 9 brigades.
5 brigades are at the front, but 2 or 3 are yet to make a move, and 4 are in reserve.
