I will say that I believe the Unioners see more eye-to-eye with the SCRA than do the Hessians, but both SCRA and Hessians are fighting against Corsairs and Rheinland.
There have been several dustups, in RP, between the two groups, mostly involving the pirating/shooting of civilians. A couple times I can remember, the SCRA have left a combined flotilla and threatened action against RHA for pirating civvies while we were around. We don't take kindly to that.
But in all alliances, there are going to be times where ideologies don't 100% mesh. It happens.
SCRA COULD be a turning point, depending on which side we help. It also could be a balancing point in a three-sided war as well, where we target the Libs first in a battle, then turn and attack RM forces when the battle is won. now THAT would make for interesting RP in the next battle.
"CorvettenKapitan, SCRA ships on scanners".
"I see them. Who should we turn and fight? The Libs or the SCRA?"
Libs"Sir, SCRA engaging RM, what should we do?"
"They took out our boys last time...watch them first".
And who knows what those crazy communists have up their sleeves really. Perhaps we could secretly back the Molly Revolution? trying to instill that government in Bretonia by destroying the BAF fleets before they can get to Leeds?
Or we're backing Blood Dragons against the Kusari government, only to install our own leader instead of theirs?
Or Liberty's president will finally fall to ... wait, Liberty doesn't have an oppressed worker's faction do they?
Or maybe we're just out to kill Junkers and Toasters?
