First of all: The SCRA will NOT fly along side any capitalist/fascist/lawful forces. not happening, period.
Now to the actual post content;)
Both the Hessians and the SCRA share a Goal. This goal is obviously to change the current order of things in Rheinland. While the Hessians only seek to overthrow the government of Rheinland, the SCRA wouldn't only like overthrow that but any government in their favor AND change the system of economy.
But the problem both factions are fighting with is the superiority of their enemies in regards of power and technology.
The war between Rheinland and Liberty will be a chance for the SCRA to help those forces to grind each other down until the very end.
The approach of the argument "SCRA fights Capitalism. NO, SCRA fights fascism more!" is, sadly, void. Both are enemies and both need to be destroyed/taken over sooner or later to get in power of the houses.
Even though the vulture theory is sort of right in a way, this war is too much of an opportunity to have one house getting away with a victory.
So what they will do is the fallowing: They will hit&run any side that takes the upper hand in this conflict, without coordinating them selfs in any way with one of the house' militaries. Since liberty is the greater military power, the SCRA and the RHA will hit their forces in the Borderworlds and Texas first. As soon as Rheinland advances in the Borderworlds, they will hit Rheinland's military installation (note: NOT war-industry) at home since its around the corner anyway.
They will continue this strategy until both navies have nothing left but to bite each other with their plain gums. And as soon this war is over, they will overthrow the gov in rheiland first (aided by VF which is quite an awesome faction, by the way. SIGN UP TODAY AND GET YOUR FREE LOKI!), squeeze every last bit of resources and work out of it (ironically exploiting the working class even more), create a military force and move on like grasshoppers to any other house of their choice. By then, every single one of them should be beaten to the ground already due to all the wars going right now.
And that's how <strike>we</strike> they will do it. :secret:
