UPDATE:
Yes, I do in fact have plans for this faction.
The idea is, have a map similar to this (just not animated, so maybe more detail):
And have the STE and ISC battle it out.
Of course, others can join, however only a single flotilla/battlegroup is allowed
And they are under the designation: volunteers
Basically, you send your volunteers
They can take up a position and plan attacks and defences.
The idea is, upon attacking via the route, the ISC/their volunteers can intercept
And a encounter starts.
Basically, a zoomed in version of the normal map,
And the intercepted forces begin a more in depth, in game based battle.
However, starfighters will play a major role.
If you don't have good defences, expect your bridge to go down very quickly.
The ISC, having advanced tech, compared to the STE, so they have shield penetrating torpedoes for their bombers.
Stealing this tech for the STE, could easily turn the tides here.
But! Don't expect just that, the ISC will continue attempting to use biological warfare.
And will attempt to destroy any and all non humans.
In fact, they might attempt to make a new TAUDIE... but who knows.

Well, here, some more info:
Two weeks after original ISC's creation (Graham talking to recon leader) :
"so, its clear they will become an issue
I need you to infiltrate this, rebellion of theirs."
"but sir! I'm just a regular guy"
"I know! Thats the point, you will be perfect for recon leader
Not only will setting this position up, and making Tau's
Allowed to apply for recon team, delay their thoughts if there is a rebellion
It also makes you more convincing! They won't suspect a thing.
Anyway, we need you to go to this location.
We are sure their meetings are held here.
All we need to know is if they are real, then, we can plan."
"yes sir."
two days later
"ah! You again, so any info?"
"yes, they exist
There is a rebellion"
"I knew it!, well, we can wiretap that hall
So good job! Dismissed."
"but sir! They are right
This, what we are doing is wrong! Evil
We can-"
"haha, you believe that crap?
Come on, they just need an exuse.
We are perfectly fine! We are good people.
Now get out of my office."
A month later, the rebellion happened.
But due to those few words "yes they exist"
The ISC had a counter-plan.
And so, set a insane man's plan into action.
To commit genocide, on a scale no-one had seen before.
Maybe if you found the Recon team leader... he could help you.
Or maybe he was drafted into the new ISC... who knows...
But yes, the ISC are very good at long term plans...
The STE not so much.
