Thanks for your extensive reply, Gary
The reason I emphasise portability is due to the need to move quickly in ambush engagements and a 63 kg platform would be a pain to move. I mis-calculated the weight of each component of the Kornet E; I was under the impression that the 1PN79-1 thermal sight included the laser designator but that's embodied in a separate system in the 1P45-1 sight-tracker. It's clear that I was wrong about the Kornet and what could reasonably be achieved with it. I believe that an improved variant of the Metis-M1 could be improved rather inexpensively to exploit its portability and lethality:
a) This Metis-M1 variant could have its guidance updated with fiber-optics -- replacing its current wire link, thereby increasing range. It has the same potential -as the Spike LR- (12.7 kg) to have a range of 5 km
b) It could work in concert with small, inexpensive tactical drones to provide an image of the targets in the battle space and the missile itself during its entire flight. Such tactical drones would be very useful with the inclusion of an auto-tracker similar to that of the Kornet-D only that it would use jam-resistant radio guidance
c) It could be provided with a top-attack mode to fire safely behind cover and exploit terrain and not be constrained by it; in its direct mode it could travel 5 meters above the ground to avoid obstructions and fly 30 meters above the ground to overcome the limits of terrain. With its 900-950mm of penetration it could destroy any MBT.
d) A soft launch ability would further increase its utility in confined spaces
This Metis-M1 variant would retain its inexpensive guidance and all its current components while gaining new abilities and greater flexibility without being prohibitively expensive.
