If Ukraine fights Russia using Russian tactics going toe to toe, they will suffer huge losses. They need to continue what they are doing, nibbling beyond the reach of Russian artillery with longer ranged artillery and HIMARS, with precision guided munitions. Once enough nibbling has occurred, like a cavity in the tooth, the integrity of the area is comprised and they can come in and mop up. Once enough of that happens, it will continue to break the will of Russians' will to fight, making gains even easier. So, that is a long way of saying I believe they will stay the course, which has been wildly successful in the past 2 or 3 months.
