Terran involvement in the Great Galactic War

The Terran Federal Republic entered the Great War in 2636 and became the principal opponent of all other forces involved in it by 2638. The Terran Federal Republic remained a major belligerent of the war until the cessation of hostilities following the August Armistice in 2647. Terran involvement started the Second Phase of the war. The Federation waged a war which was drastically more destructive than that waged prior to its entry, which caused the vast majority of casualties occurring as a result of fighting between Terran and alien forces. Immediately upon its entry into the war, the Terrans executed several operations in alien territory, the most notable of which was Operation Cinder. Following the overthrow of the Ur-Han Empire by Surben forces in 2637 and major losses against the Federal Navy in 2638, the enemies of the Terran Federation banded together in the Coalition of Galactic Defence in 2639. 
The Terran war effort was capable of matching all other nations combined for the majority of the war. The Terrans were also noted for committing war crimes and using extreme amounts of force, especially during planetary occupations. The Federal Navy notably deployed WMDs in the form of ADWs, whilst the Federal Army established internment camps on several occupied worlds to house civilians.
