I just learned today about the IA9 Tyrant's Legion list. I have the book but never bothered to read the army list. It's REALLY cool. It lets you build an army with both Space Marine and Imperial Guard but not in a fashion that's like allies, but a restrictive army list that only lets you choose certain units which have pretty different rules than you'd normally see. Anyway since I have a guard army and MANY marine armies I'm going to try this out next game I play. Hopefully my opponent doesn't read this! If anyone has tried out some stuff from this book let me know any tips or tricks you've found or fun things so I can try them out. I was really going for an army here without spamming stuff.
Huron Blackheart - he's basically a terminator chapter master with a cool lightning claw that forces invul rerolls.
Centurion - a manditory choice in 1500+, is basically a sergeant IC.
Elites - Huron opens up an elite choice from the SM codex. I chose hammer terminators and a LR crusader as a dedicated transport. No more to see here.
2x 10 Armsmen with a melta gun and a chimera sporting an autocannon. I took two of these and they're basically just normal IG. They'll be flanking and holding objectives with the autocannon.
20 Legion Auxilia with a heavy stubber and flamer. These are like conscripts with even worse armour. Luckily they're manditory! They do provide a 3+ cover save to marines hiding behind them though due to a special rule.
10 Space Marines with 2 melta guns, a fist and a rhino - Basically a tactical squad but you can take two assault weapons.
More neat mixing
Leman Russ Battle Tank with 3 heavy bolters
Leman Russ Exterminator with las cannon
Predator with las sponsons - this is unlocked by having the space marine squad.
So we'll see how this plays out. There's a lot of fire power granted by the IG units plus some heavy hitting terminators. I'm sure there are ways to alter this list out to get a lean mean fighting machine but I'm just excited to play these two armies together and see how they interact. Having a lot of AV 14 will be really nice too. It's almost like having a gunline where if the enemy comes close you have some elite units to smash them with. I encourage anyone looking for a change in their games to check this book out. I'll also encourage my friend to post a BatRep.
