Is there really any canon types or is it just the graphical update between halo 2 and 3? I ask because recently we’ve seen MCC with the Solemn Penance in it’s classic city like structures, and in Halo Fleet battles (https://shop.spartangames.co.uk/ProductDetails.asp?ProductCode=HFCV05) it uses the MCC Solemn Penance version of the CAS. So which one is canon or are there two different versions?
