not sure why this is downvoted, it's 100% correct. more specifically, a lot of NATO support following Euromaidan and "separatist" fighting 2014-2015.
after a few black eyes fighting the Little Green Men, the AFU leaned hard on NATO assistance for training and armament.
it's why the Ukrainians held out against Russia, and why Russia struggled so much -- they thought they were fighting the 2015 AFU, not the 2022 AFU.
