The video is Crossbow, a COMPLETELY different, conventional (i.e. non-nuke) penetrating weapon. Rather slick as it's effective against sheltered targets (like this A-7) or targets in the open (there's another video going around of a Russian multiple rocket launcher getting the treatment).
You are unlikely to see video of RNEP for a number of reasons.
