I maintain what I said for the walker vs laser tank. The artillery capabilities of the walker are a lot better with lower cool down, stagger and aoe. A laser tank shooting a kir'ko formation will not do much. A walker will remove the defense mode and leave them unable to close the distance.
Again, the tank is a wonderful attacking unit that will make a spearhead like very few others, but the walker is a far better defensive and position warfare tool, and it also recycle all the technologies of the troopers.
As for the mecha relevance in warfare, they can be a lot more nimble. Indeed large mecha designed for resilience are inferior to tanks, but more nimble ones can go in forests or cities (in ruins or not) or inside buildings. They are also more adapted to a human environment, because as humans we design things for our humanoid shape and hands. A mecha would be able to do as we do and hence would be better suited to go in humanoid environments. Of course they wouldn't compete in open fields with tanks.
