@pattontank12 @Undeadmuffin @cortz#9 --- And now for some Ukrainians!
Ukrainian Armies --- 1917-1944
It is interesting to see that in TL-191, Ukraine is a land deeply divided and fought over, with the various regional powers fighting for control over the land. Once part of Imperial Russia, by 1917 Ukraine was awash with violence as the Russian Civil War spilled over into the country, throwing it into chaos as communists, tsarists, anarchists, Poles, and Ukrainian nationalist all fought one another, even while the Germans occupied the country. By 1926 the fighting had finally died down to allow an independent Ukraine to be created, but deep divisions within the population would continue to endure into the Second Great War of 1941 with the Russian invasion.
With such a turbulent and violent history between the two great wars and with so many sides vying for control at any given point, it is perhaps understandable that the Ukrainian Army potentially had a bewildering amount of influences and sources for its uniforms, weapons, and gear.
The pictures here are meant as possible references to at least better visualize what a Ukrainian Army would look like in TL-191, from anywhere between 1917 to 1944.
Era --- Great War to Russian Civil War: 1917-1926
^^^ --- While some soldiers would wear Russian uniforms after possibly defecting from the Imperial Army, the independent Ukrainian government made a deliberate decision to issue uniforms to some units that harkened back to Ukraine's cossack and military past. While the rifles and gear are Russian, two soldiers wear uniforms that would be akin to those worn in the 17th Century.
^^^ --- Unlike battlefield in Western Europe and in North America, the vast plains and steppe of Eastern Front still facilitated a war of movement, where cavalry still had a role to play. In the years after the Great War and into the Russian Civil War, Ukrainian cavalry units would likely take on either traditional or modern uniforms from a variety of local and foreign sources.
^^^ --- Soldier from the "Blue Zhupan" Division, wearing a uniform derived from 17th Century cossack fashion. He wears a German belt with Russian pouches, armed with a Mosin Nagant. The soldier on the right in gray is part of the West Ukrainian Army, which was derived from men from Galicia originally recruited to fight for the Austro-Hungarian Empire, now fighting for Ukraine. He wears an Austro-Hungarian uniform with a Galician cap, armed with a Mannlicher rifle.
^^^ --- Uniforms, kit, and weapons taken from the Russian Imperial Army would likely be very common place as men deserted the army to fight of their respective homelands, taking with the them the weapons and gear they previously fought with. The addition of brightly colored insignia and ribbons may have been dangerous to wear on a modern battlefield, but may have been entirely necessary in a country wracked by a civil war with many sides, if only to tell a part friend and foe.
Era --- Independence, Guerrilla War, and Second Great War: 1930-1944
As Ukraine gained its independence in the aftermath of two bloody wars that seemed to spill over the borders into one massive conflict, the task of clamping down on guerrilla activity would be a high priority. With a deeply divided people still reeling from the civil war German and Austro-Hungarian occupation duties would include building up a Ukrainian Army under German guidance and rooting out any remnants of the communists, anarchists, Russian-nationalists, and other groups that would seek destabilize the country. With the start of the Second Great War in 1941 old rivalries and old grudges would resurface as Russians, Ukrainians, Germans, Austro-Hungarians, and Poles would once again find themselves fighting across lands still healing from the Great War and Civil War.
^^^ --- With likely German influence the Ukrainian Army might still look as varied, exotic, and disheveled as it was during the Russian Civil War, with a variety of equipment and weapons take from numerous sources. As the war progresses and with so many sides taking gear from one another just to keep their troops supplied and stocked, telling a part friend and foe would be a priority, especially during anti-partisan operations where both Germans and Russians would likely use Ukrainians sympathetic to their own causes.
I do apologize for the second half here, I can't read cyrillic so I can't give a breakdown for the uniforms here.
However due to large factory for armored vehicles built by Skoda and CKD in Slovak towns Turciansky Sv. Martin and Detva (one of largest in A-H,) they were more most of the time more then satisfactory supplied.
