The Grand Alliance

The Grand Alliance, better known as simply the Alliance, is a confederation composed of various planets across the galaxy, mostly in the mid and outer rims. It was founded from the Pentastar Alignment and most of the various formerly warring factions of the Galactic Empire uniting to fight the Imperial Ascendancy. These factions still exist as entities in their own right, governing the worlds they used to control, but the military has been combined into one united force and some degree of central government exists.

The Grand Alliance controls many resource-rich worlds and has a massive fleet, though currently the Alignment is in a bit of a decline due to political disunity, having lost worlds like Ilum and much of their territory to the New Republic and other worlds like Coruscant to the Imperial Ascendancy. Currently it controls just under 1/5th of the galaxy.

Military of the Grand Alliance
The Armed Forces of the Grand Alliance are composed of the Grand Alliance Army, the Alliance Navy and the Special Forces. It is currently one of the most powerful military forces in the galaxy as of 18 ABY.

The navy is composed of 5,521 capital ships (almost exclusively Star Destroyers), hundreds of millions of TIE fighters and their variations, and 1 Super Star Destroyer as of 18 ABY.

The army is composed of several different divisions with specialized roles, totaling up to a combined size of roughly 40 billion battle-ready soldiers as of 18 ABY.
