I'd argue otherwise about the Davy Crocketts, but that's another story.
Focusing on the mech/frame for the SAoY, Wes last said that he basically wanted a 'Chicken Walker' similar to the
ED-209-14. We've already agreed that hover and low level flight is a standard must given the setting, but in addition to that, we should likely make it a fast runner. It'll have digitigrade style legs, so we might as well take advantage of that and say it makes it run even faster. Now, I know some of you - myself included - would prefer a humanoid design, but we should work with what we got. Already, it's accurate to guess it'll have at least two 'gun pods' or little arms of some sort.
If it's 3m in height, two ADR 4 cannons with HE rounds of some sort with coaxial guns like the LASR would likely be its bread and butter. It could likely also carry perhaps 2-4 medium sized mini-missile racks on its back in addition to leg options. Swapping those out with another pair of 'over the shoulder' cannons wouldn't be a bad option either. If it'll be 6m in height, a similar layout wouldn't be too bad, with ADR 5 cannons instead, and some sort of ADR 4 autocannons in place of the LASRs. This isn't counting any point defense lasers or possible drones it can deploy though. On the other hand, that's just a generic layout too.
