They are also employing 15-16 y.o. in factories producing drones, putting them into the crosshairs. Russian leadership has indoctrinated their population to believe that their lives are worthless, and they use them in exactly that way.

Source: Denys Davydov on Youtube. I like him because he is pro-Ukraine, but has no qualms with portraying the situation as less then rosy in a lot of sections of the front and criticizing Ukraine leadership and military misconduct as well as the not 100% consistent support from the EU - 13% of our LNG is from Russia still, and Putin is using that cash against both the Ukraine and the EU.

For example, the situation in Scala brigade where they abused recruits (including deaths) and used the same "tactics" a.k.a meat waves as the russians for offensive operations. He also is critical of the Kursk incursion or Bahkmut - in Kursk, they stayed far too long (months instead of weeks) after realizing that they could not reach strategic goals and lost more personell than needed; in Bahkmut, even tho they inflicted heavy losses on the enemy, they also took more losses than they should have (and they have far less available personell than Russia, making this more painful for Ukraine than Russia, because these situations reduce the amount of people willingly joining up).

Or that some drone brigades had no qualms publishing FPV drone footage of attacks on gas stations where civilians were present. Russia is doing such things at a much larger scale, and those actions aren't a daily occurrence, but a war crime is a war crime, regardless of who commits it.

Another channel I really like is "Inside Russia" - an middle aged Russian living in exile reporting on how the russian state works and how the "SMO" is affecting every part of russian society. Currently he is on a bit of a hiatus, but once his situation stabilizes again, he'll be back for more (he had to flee from Uzbekistan to Luxembourg with his family because the pressure of the KGB that shadowed him became unbearable including making him ill - a Z-Blogger provided him documentation confirming that his hospital stint was a little "present" - and calling him the moment he checked into the hospital asking "how he's doing" and with an offer to work for the russians. The Uzbek secret service made it clear that they knew what is happening, but did not have the means to protect him. A few years back he ran afoul of Alexander Dugin on Twitter which started this BS, normally they wouldn't bother)

this strategy has worked historically. just overwhelm your enemy until they run out of ammo or men. assuming you have enough troops to throw into the meat grinder anyway.

drones changed everything though. most aren't even getting close to the front line before getting killed.

as for why they are not adapting I think it's because commanders are getting lied to about the situation in the ground. if your intelligence is bad your tactics will be bad.
