The Russians love artillery, especially when it is massed which is probably not such a good idea in today’s warfare.
Ukraine is tryin to replace their military losses with mobilization... So they’re just sending their people to death without proper training. Can’t blame Ukrainian soldiers for deserting a sinking ship.
Once we put ISIS in range of our artillery, it was over. We had to re-=learn an old lesson: it’s the King of Battle for a reason.
