Strafing implies—again—flying low over a potentially heavily-defended target. If even a handful of ground troops in that convoy are carrying MANPADs it would be suicide, and that's to say nothing of self-propelled anti-aircraft guns that are almost certainly accompanying the convoy.
Again, there are probably far more urgent targets for the Ukrainian Air Force than a convoy that hasn't moved in days.
> No, this convoy would be an obvious strafing target. I'm disappointed that the Ukrainians didn't even attempt it. Or we haven't heard about it.
I wouldn't be surprised if the convoy had the equivalent of a 1000 US Stinger AA missiles or more. It's not with strafing if there's too high a chance the jet would get shot down.
As a layman, I'm guessing the only things worth the risk might be some operation that could potentially trap the convoy (e.g. between two knocked-out bridges).
