Note that in general media only covers stories that they want to see covered. Especially in a war, there will definitely be explicit pressure on how the war is covered, and most journalists are anyway aligned with their home countries even when there is no government pressure.

So just like you wouldn't expect RT to cover Russian losses except perhaps in the most general terms, you shouldn't expect our own countries' losses to be covered by our own media other than in passing (even if it's obviously not as directly controlled as RT is).
