This is one of the most recorded battles in history. There have been some huge fuck ups like a base of foreign volunteers getting blown up because they made a video with metadata that had geolocation. BUT, mostly there are a shit ton of drones and also Russia has advanced planes that trace radio transmissions, phones aren't that big a deal.

There's even an army of Chechnyans called the 'Tik Tok Battalion' because they stream so much.
