I'm honestly not sure how badly we need soldiers? It seems like, per the Fallout phases, the revolutionaries are already overrunning most of old US, and certainly in a more stable position than the remaining White governments even before we add this round of additional uptime supplies and aid. I'd prefer to go for native revolutionaries specifically to shore up the native organizations in the west and hopefully encourage cooperation and communication between revolutionary states rather than more soldiers to help the military efforts in the east. Unless you think we're overall better served by a quicker victory in the core US territory? Decisively crushing the White governments would definitely help discourage any European interventions, and limit the scope of the post-revolution British puppet territories.
