Good information guys.
However VT-4 probably shouldn't be compared with Abrams. 50T tank and 60T tank.
My personal opinion of tanks ranked over years of reading material and trying to remember the overall whole. For what it's worth just entertaining hopefully but not too serious.
T-14 (although not totally ready just yet)
K-2 (this is surely a bit more of a personal guess than from attained information because there isn't that much)
Improved Challenger 2
Leopard 2A6/7
M1A2
AMX Leclerc
Type 99A (third version)
T-90M
Challenger 2
Merkava 4
Type 99 (second version) and VT-4 overall balance is similar
Type 10 (like lighter tanks the protection is very minimal and firepower isn't much better than those on top of it)
T-84 Oplot M
Arjun 2
Type 90
Rest are relatively equal low tier tanks like various modern T-72 and T-80 and Type 96A. All of those would be considerably lower than the above list.
Low protection and lighter tanks typically would have better mobility and driving range. Anyway firepower is first priority, second is mobility, third is protection but the ones nearer the top are all clearly better protection but not much worse if any worse in mobility due to far more powerful propulsion units. Western tanks have firepower advantage due to better guns and still better ammunition despite huge improvements in Chinese ammunition over the last ten years. Russian ammo of modern versions I'm not familiar with but surely improved as well. Our guns and ammo still don't match latest Euro and American though.
Honestly ever tank on that list is close enough that the important factor is really the crew, the situation, the numbers, the strategy and tactics, and of course supports. Infantry and drones or helicopters and air support or none. Money too of course as usual and operational readiness. Buy and pick what suits your situation.
AFAIK There are not three versions of the ZTZ-99, only two. ZTZ-99 and 99A. I would place Pakistan specific VT-4s only slightly behind the 99A. The former leads in technological and C4I aspects while the latter leads in firepower and protection. I would place both above the Leclerc because the XLR
variant of it apparently still isn’t in service, which is quite an upgrade for the aged tank.
You’re right to say that the K-2 is mostly just a guess. There isn’t enough on it. I’d place the T90MS provyv 3 above all those tanks except the T-14, the Leo 2A6/A7 and the M1A2CSEPV3. Russian metallurgy, ERA and ammunition are still some of the best.
I’d place challenger 2 at the bottom of the list due to its rifled gun, however the improved challenger 2/Challenger 3 would place pretty high up with the armor improvements and the 130MM smootbore.
My list would look something like (speaking purely from a capability standpoint)
T-14
Leo 2A7+
M1A2C SEP V3
T90MS Provyv 3
Challenger 3 (not in service yet)
K-2
ZTZ-99A
VT-4P/AMX Leclerc/Merkava IV Windbreaker (the trophy APS plays a big part here)
ZTZ-99/VT-4/Challenger 2/T-84 Oplot M.
Al-Khalid-1/ZTZ-96B
T90S/Al-Khalid
Arjun MK-1A
And all the legacy tanks below these.
I don’t put Japanese tanks in the list because they’re very specific in their roles. If anything any list like this is purely speculative and redundant because tanks unlike fighter jets or ships don’t fight in a single, level playing field. The air and the sea remain pretty much the same, the ground on the other hand changes a lot. Each country designs tanks with their specifications, terrain, logistics and economy in mind, so while one tank may be better for one country, it certainly won’t be for another.
Secondly, if you go into detail on these tanks, you’ll see that literally none of them is balanced apart from the top 3-4 tanks. Each has some major flaws and some redeeming qualities.
Design wise I’d say Chinese and Chinese origin tanks lack the most, while protection remains an issue is basically every Asian tank (especially side protection). Ukraine has very weak ammunition even if they improve their tank. Russia (before the T-14) has had rather poor transmissions in its tanks.
The countries that are mass-introducing Hard kill APS systems are taking a massive leap in regards to tank protection, which would make even a mediocre tank a massive threat to a much better one.
