Footage reportedly shows Ukrainian troops knocking out three Russian tanks in quick succession with US-supplied FGM-148 Javelin anti tank missiles. Interestingly, you can see the Ukrainian soldiers utilize the "fire-and-forget" capability of the weapon system as they fire the missile and run for cover long before the munition makes a hit. Once locked on to target, the Javelin will continue to autonomously track and change its flight path as necessary with no need for the gunner to keep eyes on the target.
