I've been following Gonzalo Lira's channel on YouTube. He suggests there are two battles going on, one on the ground and one in the media. All the Ukrainians have left is winning in the media, as they probably cannot defeat Russia on the ground. So Ukraine has an existential need for incriminating video and images of Russian atrocities. They need this imagery to get other nations militarily involved. The problem is that Putin wants to have as small civilian casualty numbers as possible. So we should expect and watch for Ukraine to manufacturer fake video and images. I actually wonder if that's the reason Russia has painted the letter Z on the tanks and other military vehicles. It makes it a lot harder to reuse old footage where the Z has to be inserted somehow in editing.
