Ucranian commanders are absolutely delighted. They say that not only is this able to vary cisely take out these vital russian nodes well behind the front lines, it's also able to stay immune to what we call counter battery fire. We call that shoot scoot. And the ucranians are using it very cleverly jacent. So yes, they can adapt, but any adaptation is going to jam up thei logistics, is going to caule some other problem. Any what do you mean by that? Well, extent, they can disguise their sights. But that is very challenging for the russians.
