For those who have only seen the headline:

Nearly three months into the counteroffensive, the Ukrainians may be taking the advice to heart, especially as casualties continue to mount and Russia still holds an edge in troops and equipment.

U.S. assessed Ukraine's counteroffensive strategy and made recommendations, and now Ukraine is adjusting its strategy accordingly. The headline makes it sound like an endemic issue. Some analysts think it's too little too late, but I wish them the best.
