The Update 1.2.3 for Civilization VII has unveiled Assyria as a new, playable civilization via their Right to Rule Collection. A small thread on what has been added:

Assyria's unique civilian unit is the turtanu, a high military official attested from the Middle Assyrian period onward. They were something like a Commander-in-Chief, with additional civic responsibilities. The most famous example was Shamshi-ilu, who campaigned against Urartu in 780 BCE.

The unique military unit is the magarru (which should be 'mugerru' in Assyrian; 'magarru' would be Babylonian and not in use by the 1st millennium BCE), a two-wheeled chariot known since the 12th century. These things were horrifying to confront and a major part of the military economy of Assyria.

Their unique ability is the 'treasures of Nineveh', which allows Assyria to gain a technology when capturing a settlement. This relates to the Assyrian practice of incorporating the libraries and archives of cities upon conquest. The library of Ashurbanipal is the culmination of this practice.

The unique quarter is the Ekallu, or palace. It is created by constructing the royal library and citadel together. The notes here are great.

The civics are the birtutu, kibrat arba'i, and tupsharrutu, which are all nicely conceived and hold some cultural and historical nuggets. I appreciate especially "over the course of 12 years, boys and girls were rigorously trained in cuneiform script;" yes, women learned, too!

Further in the Civilopedia notes, however, there are some alarming suggestions, such as Sumerians coming from the Indian subcontinent, Sargonic rebellion against Sumerian rule, the centuries after 2150 being a dark age, Assur having free trade, etc. These points do nothing but misinform readers.

"From this day forward, your pronouncement shall be unchangeable, to raise or bring low - these shall be in your hand."

These words are for Marduk at the onset of the fourth tablet of the Enuma Elish, when he accepted to be the divine avenger and bind Tiamat, saving the lives of all the Anunnaki. 

In Akkadian:
ištu ūmim-ma lā innennâ qibītka
šušqû u šušpulu šī lū qātka

A copy of this tablet was accessioned in 1882 by the British Museum, discovered by Hormuzd Rassam. Link to that artifact (click here).
