Meanwhile, occured to me.
With all laughs and so on - if M2020s are really in service - if we do an assessment (by formal attributes), it may very well be one of the most advanced tanks in the world.
Joke we may, but neither South Korea, nor China, nor Japan has active tanks with APS - and Russia only barely so(not fully operational anyway). Nothing is immediately wrong with it in other aspects as well. 115mm gun isn't a crime (especially with the possible length of its dart, which is longer than for classic Ru/CN 125mm guns), and while an integrated commander's sight instead of a panoramic one is a crude solution - it is by no means wrong.
152mm ATGM will probably brutpen most things that can be encountered as well - even without top attack(which NK can do); again, just two exposed rockets it may be - but it is likely stronger than autoloader-limited 125mm GLATGMs of Russian and Chinese tanks.
