between you and your enemy, just like WR/TE's push-pull technique to creat separation in football. But you got be very physical by doing that. Ukraine clearly lacks of power to make a push in their retreat. Russia sensed that and certainly won't give Ukraine a break. It's expected Russia
will stop after breaking Ukraine's 3rd defensive line. Because from the contour topographic map, that area is relatively higher, Russia will be happy to stop their advance after occupying that higher area. I am talking about same fight the Newsweek article talks about.
