"Super Sonic Showdown" 1500pts Cadian vs Emperor's Children

I finally got to have my first game with my work in progress Imperial Guard army.  I could only play with what I have already brought so could only do 1500pts because I don't quite have 2000 yet but I really wanted to try them out.

I was playing my friends Emperor's Children, who I hadn't played yet this edition and he had some new Forge World Sonic Dreadnoughts to try as well.

We were playing The Scouring with Spearhead Assault.
