“Is there a lack of war corespondents in this war or is media not reporting what they find?”
It’s BOTH of those things and the fact nobody in the west gives any credence to Russian journalists. And in many cases with good reason...like Ukrainian journalists they report what they’re told.
And neither side will allow independent journalists on the front lines, with the occasional exception for Ukraine who wants to highlight some supposed Russian atrocity.
We know less about the situation on the ground than any war in the last 100 years.
The only thing we know for sure is that the propaganda is so thick you can cut it with a knife.
And you can watch first person views of the fighting from the GoPro cameras some of the soldiers wear.
