- Baran War - 914.M40-224.M41
- "Balur Secundus Strike Force" - 7th Co. only smash-party.
- The Defence of Hyth (994.M41) - Stopped a Hive Fleet. Alone.
- Fall of Medusa V (999.M41) - 4th Co. got honors and fought eight other races in the conflict.
- Zeist Campaign - Tau Vs. Space Marines. Matt Ward wrote it so you can guess how it went. Considering how much the Tau are wanked, it’s probably for the best that Ward wrote this one.
- The Indomitus Crusade - Can't have the Ultramarine Crusade without its successors right?
