I've got the big Trumpeter T-98. It's not a horrible model, but it's not anywhere near in the same league as the new large-scale models from Tamiya or Verlinden. Think the old 1/25th scale Tiger I -- without the interior.
Russian tanks (and their Chinese knockoffs) just have not kept up with Western technology. There is a lot of trumpeting coming out of the Third World and from Russian armour fans about how the Western tanks are all hype and the new Russian-style vehicles are so great, but a simple observation of the warfare in the Middle East over the past 20 years or so is all that's needed to come to a more realistic conclusion.
These large land-based empires have such huge borders that they must produce vehicles in vast numbers, and transport them over small bridges or poor roads. They just cannot produce tanks in sufficient quantities, and meeting those size limits, and still make tanks that can challenge the newest generation of Western tanks.
Not only that, but they don't spend nearly as much on the military as we Americans do. We are 5% of the world's population and spend 50% of all the money spent on earth on war goodies. [:0]
These radical new Russian designs are all based on Soviet era platforms that are proven failures in tank to tank warfare on the modern battlefield. Draw your own conclusions.
