They are allied to their respective sides; the only restriction is that the Reds cannot operate outside ORT.
Whichever side controls Moscow at the end of its turn builds units there.
Otherwise, each side can place one new infantry in each ORT it controls at the end of its turn.
I’ve also considered making Karelia/Petrograd a production centre, so its possible both sides may control a capital.
Regarding cash, only a faction controlling the capital collects and spends; the other is, in effect, treated like any other power that has lost control of its capital. If Moscow is contested neither can collect and build there.
All ORT are “home” for Russian factions.
At the time of the Revolution, those units in Moscow, Karelia & Tartarstan become Reds, other Russian units remain Allied.
Both factions remain in the game until the end; even if one is eliminated its tt can be liberated by its allies.
Moscow counts as CP victory objective if the Reds control it.
