And that’s why I say most of all the unique stuff can be found in WW2-50/60s.
Sure most nations have one or two things still like the Belgium Cockerill turrets or the Canadian LAV line. But the bulk of their stuff comes from that era.
And yes there are nations that have (or are regaining) a full domestic defence sector like India, South Korea or Poland in the modern day.
PRC and ROC are both still considered China.
You can’t say the same for Ukraine and Russia.
Even though they’re both at war with each other, the circumstances are different.
Ukraine isn’t as recent of a country either compared to what others might say.
No one is getting any Su-30 versions any time soon…same with EFT, Rafale and F-18. I would expect a c&p for China from Russia. So whatever is closest to the 27SM…probably J11B
