In occupied Kherson, a man who performed at weddings before the war said he had pivoted to planting explosives under Russian soldiers' vehicles.And outside the city's airport, a tech worker snapped photos of the enemy's vehicles, collecting intelligence that was then promptly used to blow them up.These stories were shared Wednesday by The Wall Street Journal, which reported that regular Ukrainians, using simple tools like smartphones and the messaging app Telegram, have proven very useful to their country's intelligence gathering processes.The Journal said that few have been released, as civilians are rarely exchanged in Ukraine and Russia's prisoner swaps.When putting together teams to send to various places, "we try to find people and to integrate those people into those autonomous groups who know the local population and actually maybe were originally from those places, who have some relatives there, who have communication, who can be acting like a pathfinder," he explained."
