Not very bright.

Was wondering about those friendly fire incidents that keeps cropping up from Russian units - one unit got arty on them by the Ukrainians and then they requested counter-fire but their own side dropped it on them instead.

Or a Ukrainian unit could get access to a Russian telegram account and then send malicious requests.

At least they would use code words but with the NSA supplying intelligence and most new units deployed are full of mobiks , have little hope for them.

9r they could get access to the requesting account and send artillery.
