The maximum effective range of the Stugna-P ATGM system is roughly five kilometers. This video shows the Stugna-P scoring a direct hit against Russian armor at it's maximum range.

The location that this video was filmed is unknown. The date was left at "recent." The only proper context we have is from the language the fighters are speaking, which is Georgian. That would possibly mean that these guys are from the Ukrainian Foreign Legion's Georgian unit.

Regardless, this is one hell of a shot.
