BTW, the same blogger also wrote a post recently that specifically discusses the differences in how Russian and Ukrainian forces employ their artillery. Also worth a read:

(I would generally recommend this entire blog for those curious about the tactics and the logistics of the conflict, because it's one of those rare cases when a guy who is directly involved in the war, and has a long-standing reputation as one of the prominent hawks, is consistently writing posts that are critical of his own side - which criticism is far more likely to be accurate than propaganda from the other side.)
(For the curious, here's a blog post from the Donbas separatist side that talks about drones and their combat use and maintenance, among other things: https://kenigtiger.livejournal.com/2140772.html)
However, Ukrainians have learned to embrace the drones in 2014-15 already, and have had a lot more experience with them since. Russia is still learning that lesson in the field.
