That video was so well done. Thanks to WarTranslated for the translation, and to you BamaATL for posting it.
Chasiv Yar has been a critical point of defense for Ukraine. I thought at one point it might get overrun, which would have been a disaster. I don't know what happened, obviously, but from reading it appears they rotated out some of their veteran troops, and the new units weren't able to hold the Russians very well, so UAF had to send in reinforcements.
The 71st Jaeger Brigade is a new unit, formed after the invasion and initially part of the reserves, but they've already been decorated for work in the Kharkiv offensive, and it looks like they're doing great work at a critical juncture for the defense of Bakhmut. In all honesty, in many ways Chasiv Yar is a more critical defense point than Bakhmut itself because it's located on a hilltop overlooking Highway T0504, "The Road of Life." There are some natural fallback positions from Bakhmut where UAF would still maintain the higher ground, but if Chasiv Yar falls Ukrainian military would have had to fall back much farther to set an effective defensive line. Based on other analysts.
Good stuff.
