As the British heritage is probably decreased or downplayed in Draka, I am curious to how society might develop.
I could see uniforms changing to get rid of their former pride in being a british "dominion" and establish themselves as more of their "empire." I think a neoclassical craze will come soon - the soldiers might now use more Roman influnece like the oringinal Drakaverse, especially with Naldorossen introducing the "color blind" slavery that attracted them to neoclassicalism.
I could see pimped out Neoclassical architecture with perhaps futurist elements as well.
In terms of Draka parade uniform, to emulate the romans, I could see them adopting Animal pelts to an extent as well as other civilizations they fetishize, such as Ancien Regime France.
Now the Draka have begun to become less Anglo Saxon and more you know - the "race."
Thus I see them in pimped out uniforms and likely unsettling attire, architecture, and whatnot to add to their increasingly quasi alien nature they are developing at this point.
Also Draka architecture I could see getting more pimped out.
To emulate the romans with more "modernization,"this is an idea, although think to a higher extent.
Animal pelt "parade uniform." (I do think the pith helmet will be replaced over time as British influence declines with something Corinthian or Roman looking, given the likely coming neo classical influence, as well as probably viewing pith helmets as too soft, preferring a good old neoclassical helmet with a great bright brush plume inmitating illyrian/roman style. I do think Corinthian for Draka parade uniforms would be cool, as it symbolizes their spartanic heritage, and it also separates them from softer european powers and will fit well with Elvira Naldorossen's ideology of Societism.
Later era Draka parade helmet? Granted the uniforms will probably look similar to western powers otherwise, in terms of the tunic and breastplate (though a more ancient style breastplate can be adopted, I dont think the tunic will change to a straight up toga.)
Also this I feel is a good combat uniform (for around wwii era of this timeline due to technological advance being faster as well as draka generally being evil geniuses known for having very up to date technology giving them an edge) ... Both because it is pretty canon based on the cover used in marching through gerogia, plus it gives me a "more evil Rhodesia" (I think nazified, giant, Rhodesia as Draka) vibe that the draka has.
Yeah just some thoughts.
Edit: given the fact that tech is more advanced, by the modern day in this timeline both sides will probably be using power armor to an extent for combat purposes, if not universally eqiuped. I picture a sort of fallout aesethic for this cold war for some reason in my opinion. Though the power armor will probably look more realistic and less comical than the BOS armor, I mean in term of the political aesethic and style in general, a atompunk.
This is an OTL aussie concept for a future suit of power armor, so it would not look like fallout universe at all unless heavier than this for certain units. Just to put things in perspective, the modern soldier by 2019 in this timeline might look like these above.
