In this video I look at that initial missile campaign, the way the campaign evolved subsequently, and what lessons other countries might take from the war to date. I also address the question of sustainability - is Russia running out of these precision munitions, and to what extent do their production facilities have the ability to compensate. One thing I do want to say as well, is that while I try and take a reasonably detached look at issues like this, I want to make clear that discussing the performance of these systems shouldn't take away from recalling the very real human impact of their use, particularly against civilian targets or in built up areas.
