Also, unsure if this was already asked, but how do walkers organize and operate? Do we operate similar to modern day armor companies? Combined arms approach like today's mechanized infantry? Do we operate alongside traditional tanks and jets or are do we operate on our own? 

Questions pertaining to Raptors specifically, the walker mode is incapable of flight, so when we change mid battle I assume we slow down and go close to ground before changing but how does walker to fighter work? Do the walker forms move fast enough to jump and perform short takeoffs without a dedicated runway? Or are they VTOL capable?
