M60A3 TTS (China)
This vehicle has a DIRECT counterpart in the US tree, even sporting the same name and BR (9.0). The issue lays in the Chinese version being objectively worse! It doesn’t have M774 as its top ammunition, being forced to use the nerfed M735 resulting in 25% worse overall penetration - this makes a very big difference, especially since 9.0 often gets pulled into 10.0 games. Another issue, though not as critical, the US version also is outfitted with ERA protection, which the chinese version also doesn’t get. Please add the M774 to it and consider putting the ERA as an add-on armor modification.
ISU-122 5.3 → 5.0
The KV-122 is the same chassis, same gun, same armor and also the same BR, but gets a fully traversible turret over the ISU. The difference in utility between a vehicle with a forward-locked gun and one that can just peek at 45 degrees, fire a shot and use the amazing reverse to be behind cover before the first even gets its gun on target, is massive and cannot be overstated.
M113A1 (TOW), China, Italy, Israel 8.3 → 8.0
Currently these vehicles, which are merely a missile tube on a simple tracked platform, are the same BR as fully fledged IFVs like the Bradley and Warrior. Let me list what these two have above the post’s subjects: proper APDS firing autocannon, better moblity (both forwards and in reverse), better armor (do not die to .5 cals and they are not overpressured by artillery landing a few meters away), gen 1 (or even 3!) thermals, stabilisers or very fast aiming speeds, fully traversible turrets (M113A1’s have a limited firing arc).
What do M113’s have in comparison? 200mm more penetration on their missiles against the Bradley or better depression against the Warrior (which actually has BETTER missiles!). This performance gap is just unnecessarily large.
For even closer comparison consider the M901 (USA), the same chassis, but, again, a fully traversible turret, being able to fire two shots in succession, thermals and even better depression! The M113A1’s only have a lower profile over it!
Tiger II P, M26, IS-2 (1944) 6.7 → 6.3
Tiger II P and M26 are in a very weird spot currently, with direct upgrades (Tiger II) or extreme capability differences at the cost of HP/t (M26) sitting at the same BR. Why would I play the M26 when I can play one that’s invulnerable to long 88, or one that massively improves both the turret and cannon? Why would I weaken my turret face to below 120mm from 160mm+ for zero benefit?
The plight of the IS-2 is slightly harder to see, but compared to its other heavy tank contemporaries it’s clear to see that it comes out the worst. Having TRIPLE the reload time of a Tiger II and 1/3rd the depression of the US ones. It’s turret is only better than the II P, and can be penetrated by guns 2 BRs below it! And even if not, the towering cupola will take care of telling the enemy where to shoot. The only thing this tank offers is overpressure, but why bother when others will have better positions, will hit your weakspots first and will have triple the chances even if they miss?
