I just had a couple of very good questions from johnharry, so I suppose I had best consider that fate's kick in the butt. My book manuscript is out the door, so no more excuses to revive the timeline:
1. What uniforms would the Germans and Russians wear during their 1944 war? Does the German Army keep the Stahlhelm? How similar is Russian gear to that of the Soviets? What about Mitteleuropa states, has the "Prussian/Wehrmacht" style spread to them in terms of doctrine and aspects of uniform?
Right, the German tradition is going to be effectively unbroken and buoyed by victpry, so the uniform design will be in many ways more 'Prussian' than IOTL. There will, however, be a strong undercurrent of frugality and simplicity that IOTL did not share, a sense of 'mehr sein als scheinen'. No shiny collar tabs and towering peaked caps, no scary and ominous all-black, and no more shiny cuirasses and gold-braided 'regimentals'. Generally, the post-1908 army will have a relativel weimarish appearance and keep it well into the 40s, when the impact of the next war creates a more technology-focused image. Generally, the German look is going to be:
1908-1940s: tunics and straight trousers in 'feldblau' (dirty grey) with large pockets, turned-down collars, soft-top peaked caps, tall boots (grudgingly giving way to laced ankle boots as time progresses) and grey wool greatcoats. Parade togs are single-breasted tunics with stiff collars, cut infamously tight.
1950s-1980s: camouflage battle dress with wide trousers, short, high-waisted jackets and long top-layer protective wear (greatcoats, but also parkas or ponchos), soft-top caps (tech branch forage caps are favoured) and laced boots. Parade dress still features riding trousers, tall boots and the classic Prussian blue tunic, though cut in a more flattering modern fashion with lapels. Peaked caps for officers.
All armies of the immediate German bloc copy the style to some extent or other. Austria-Hungary cultivates its own, but it has many institutional similarities (and better boots).
The helmet of the German army is not the classic stahlhelm. There are two types, the Sturmhaube, which is riffed off the Pickelhaube and is similar in weight to the French Adrian, and the pionierhelm, which is similar to the IOTL's Stahlhelm. Both designs continue to be improved, and both have adherents through the force, but typically the heavier design is given to trops that don't march much (heavy artillery, anti-air, engineers) while the lighter kind is given to infantry and armour. Soldiers have individual preferences and swap. only after the second war does the army fully switch to the 'heavy' model.
As to the Russians, they are institutionally very different. The field gear is subject to similar constraints (the need to produce large amounts on a strained industrial base), but that is the extent of it. Russian soldiers will be seen in blouses and wide trousers, many varieties of boot, and extremely generous greatcoats. After a brief flirtation with the bogatyrka, the army retuirned to the classic fur cap. Where that cannot be supplied, peaked caps are favoured. But for parade, the Russian style is consciously ethnic, colourful and bright, even extravagant. Colonial, you might say. More Bastille Day than Red Square.
