When you say can someone provide an actual description, i assume to your earlier question, i may be wrong though, sorry if that's the case.
There are many hurdles and obstacles to creating a robot such as liberty prime, as such in a nutshell they are overcoming the enemy fire by either rendering conventional arms obsolete with advanced plated armour, render firepower negligible through the usage of micro reactive armour plates, or by creating a rapidly oscillating electromagnetic field which would theoretically deflect conventional fire. The next problem to address is powering the damn thing. Any sort of energy source would be a significant weak point. The most likely sources for power would have to one of the following, a miniaturised nuclear generator, high capacity battery, or modified petrol. The nuclear generator runs the obvious risk of going critical. The battery and petrol both are fire hazards and would leave such a weapon vulnerable to incendiary and explosive weapons. We also must consider the merits of such a weapon. It would be a high priority target on the battlefield and in today's wars of drone and air strikes, it simply would be a money sink.
All flare squid or all harpoon mobula?
