its a bit political there ... hessians are not very fond of rheinland - and certainly not fond of liberty invading ( or however the propaganda is done in rheinland ... after some time, you won t know who started, you just know who wants to end it )
aiding rheinland would follow the principle that my enemies enemy is my friend - which can also turn to my enemies enemy is also my enemy - and i ll pick either of them when they re weak enough.
but its not about hessians for that matter.... - lets assume that the hessians DO aid rheinland against liberty in one way or another....
one would have to ask .... "who are the SCRA" ... deep down. - they are basicly a smallish faction that claims to have or regain the authority of not only a house - but the prime authority in sirius. - that is what the coalition tried to achieve in Sol - and that is probably the long term aim here, too.
how far would they go to achieve such a goal? - as a semi lawful group ( and - like the dragons the SCRA will hardly refer to itself as a criminal organization.... unlike the corsairs for example, who know full well that they are pirates - and proud to be ) - they might have a moral codex - no matter how twisted - but they might have one... ( one part of it is that they don t harm civilians for example )
there are too many "what ifs" in this question - too many variables for such a complex matter to weigh against each other. - the SCRA would not openly aid a pirate group but would maybe mutually give moral support ( and other secondary support - possibly even fighter and equipment - IF the hessians needed that sort of stuff ... which they don t ) - they might act as forward bases for hessians - but far enough away from the frontline .... but the hessians are better equipped in every department AND larger than the SCRA. - the hessians have their own fighterline from a LF to a VHF/bomber - they have a gunboat, a cruiser ... the SCRA has little to offer such a group.
furthermore, hessians are trained due to the long war against the corsairs, they are probably quite rich, too - due to being the 3rd largest sirius pirate faction - they even do a lucrative trade with diamonds ( and some special commodities, too )
i think the SCRA would bide their time - watching very closely how the conflict goes. - i my opinion, they wouldn t engage - other than in the role of a vulture, picking on those that are down already, - not cause they cannot do something else, - but cause getting involved more might cause more problems than it solves.
if the SCRA went against liberty too much - liberty might focus on the SCRA - and even an expedition corps of liberty could harm the SCRA seriously. - liberty deploys a powerful secret service, has a huge fleet - is much more advanced technologicly and can afford to fight on more than one border - or at least.... thinks it can.
