Here's the country tags I was looking at creating for a Russian Civil War scenario, along with (to keep this reply somwhat relevant) some stabs at political values for them.
Soviet Russia (SOV)
Dem/Auth 1 Left/Right 8 Open/Closed 1 Free/Central 1
Standing/Draft 1 Hawk/Dove 10 Interv/Isol 8
(Free/Central - "War Communism" was the most extreme Communist economy possible, which even threatened to make money obsolete. Standing/Draft of 1 represents the Soviet's tendency to rely on draftees and NCOs; officers tended to either rise from the ranks or be hostages to the Cheka. The standing/draft score would migrate slowly towards 5 through events; Trotsky's reforms of the Red Army and the nationalist effects of the Polish invasion.)
White army factions:
Volunteer Army (VOA) (Denikin and later Wrangel's armies, based in South Russia)
Dem/Auth 3 Left/Right 2 Open/Closed 8 Free/Central 7
Standing/Draft 10 Hawk/Dove 10 Interv/Isol 8
Denikin's faction was "Old Russia" personified. The extreme standing/draft score represents the top heavy nature of the Volunteer Army; in many cases fighting units were ALL ex-Tsarist officers down to "private".
Komuch (KOM) (Kolchak's armies, based in Siberia)
Dem/Auth Variable Left/Right Variable Open/Closed Variable Free/Central 7
Standing/Draft 8 Hawk/Dove 10 Interv/Isol 8
The variable nature of Komuch's scores are because in the middle of the Civil War Kolchak was installed as supreme ruler in a right-wing coup. Prior to that the Komuch was the closest thing to Russia's "legitimate" government in Western eyes and composed mainly of Mensheviks and SRs, which roughly are equivalent to democratic socialists.
Iudenich (IUD) (Army of Iudenich, based in Estonia)
Dem/Auth 3 Left/Right 2 Open/Closed 8 Free/Central 7
Standing/Draft 10 Hawk/Dove 10 Interv/Isol 8
Using the VOA values here, since in reality Iudenich's army didn't last long enough to install a viable government.
Successor states: Poland, Lithuania, Latvia, Estonia, Finland, Hungary, Czechoslovakia as per HOI2. Hungary could potentially suffer a Communist revolt through an event and join Soviets (the Bela Kun government of 1919). The Czech Legion of course will have to be portrayed somehow. Poland invades Ukraine in 1920 and the Russians later end up outside of Warsaw before forming the WW2 era boundaries; this was a full-fledged war that was fought as the Civil War was still ongoing.
Ukraine (UKR)
Ukraine's values would be all over the map since they suffered governmental changes at an almost monthly rate, and also were the main battleground between the VOA and the Soviets.
Georgia (GEO)
Dem/Auth 8 Left/Right 6 Open/Closed 8 Free/Central 5
Standing/Draft 5 Hawk/Dove 2 Interv/Isol 1
The Menshevik government of interwar Georgia, basically isolationist.
Azerbaijan (AZE)
Armenia (ARM)
Siberia (SIB)
Nothing really for these yet, as they existed only nominally (and "independent" Siberia was primarily a Japanese excuse for occupation)
Lots of central Asian states existed briefly as well, but there's no real reason to include those.
Bandit states:
Nestor Makhno (MAK) Anarchist who controlled hefty chunks of the Ukraine
Dem/Auth 10 Left/Right 10 Open/Closed 10 Free/Central 2
Standing/Draft 1 Hawk/Dove 10 Interv/Isol 10
The Dem/Auth score - well, they WERE anarchists
Realistically, there never really was a "Makhno" government as Makhno's group were more partisans than nation-builders.
Ataman Semenov (SEM) Siberian cossack bandit, Japanese puppet nation
Ataman Kalmykov (KAL) Siberian cossack bandit, Japanese puppet nation
Dem/Auth 1 Left/Right 1 Open/Closed 1 Free/Central 10
Standing/Draft 5 Hawk/Dove 10 Interv/Isol 1
Both of these states existed solely to enrich the pockets of their leaders. Kalmykov was also literally insane.
Anyway, hope that is helpful. This may well be too many tags to reserve for this, which is why I was planning on having this be a self-contained scenario.
