1. How many photos from the war have you seen of farmland? It's not exactly the prime battleground.
2. We can assume that you can recognize winter wheat at this stage from photos not focused on the crop? It, of course, looks like someone's dead lawn when it first emerges from it's winter rest. Hard to differentiate from any other grassy area unless the photo has a lot of detail.
On that note, I started looking at some random pictures after I read your comment. I came across this one[1] of a field. Wheat or no in your opinion? In my opinion as a winter wheat grower: I have no idea. Maybe.
