As the smoke cleared the battlefield, we were left witness to a disaster of
unprecedented proportions. NATO's most advanced tanks and armor were left as
smoking ruins:

The most shocking development was the closeups revealed that these weren't just
any NATO tanks and IFVs, but were in fact some of the most advanced upgraded
variants. Many of the Leopards destroyed were not the older 2A4s but in fact the
much newer 2A6s, which are some of the most advanced tanks in the world.
