Those are going to be the extra supliments. There is quite alot of fluff and fleet lists for those individual conflicts. (Before you read further there is an alternate time line for human history that you have not read yet.)
For example
The Earth Akoran War
Gives a more detailed timeline of the war including important battles, important ships and important commanders.
Replaces the UNE fleet in the primary book with the following
Commintern Fleet
Commonwealth Fleet
European Union Fleet
United States Fleet
The 3rd Fleet
Another fleet I am not willing to detail here.
The Akoran Imperial Navy
The Akoran Imperial Guard
The Horloth
The Decoran Republican Navy
Also hints as to how the timeline will progress following the end of the Earth Akoran War.
The Next Suppliment will detail the Andromidan Fleet, The Federated Commonwealth Fleet and three new alien fleets. I am not going any further with this one.
The Next Suppliment will be held during the First Intergalactic War which will detail fleets for (5) races that do not exsist any more and for the Nan'Tra'Ki, Zentreb, Zevorans.
Early fleets for the Akoran Navy and Imperial Guard.
Early fleet list for the Andromidans
Resistance fleet lists for the Terrans.
The final suppliment will be held during the second intergalactic war which will detail all of the races of the Galactic Core.
