Just in case there weren't enough suits of power armour around, the 40kfightclub and AFK Games are starting a new Babad War campaign. Rules are fairly simple even though they aren't fully defined. Pick an army, paint them up, play some games. After looking at the various color schemes for different armies I settled on the Mantis Warriors. I've never painted a green army before so that should be interesting. The other thing I wanted to do on the Space Wolves but never did was more intensive weathering. Mantis warriors seem to be a good source for this as well since their fluff is that they have been isolated and poorly supplied.
They are also veterans that excel at guerrilla warrior as shown by their chapter tactic, every power armored, infantry squad that doesn't have a transport gets infiltrate. Which is cool until you think about it. You lose a ton of mobility and there are a lot of times you don't want your basic marines so close. It is however, cool for things like devastators, sternguard, and multimeltas. Like my space wolves, this will mostly be a painting project but those loyalist scumbag need to be stopped. I know I want a couple of things in the army. Techmarines (probably with a cannon), a contemptor dread (although it will probably count as a regular/siege one)
I’m thinking something along the lines of:
Mantis Warrior Librarian
Sternguard with combi’s
Vanguard Veterans on foot
3 tactical squads, 1 drop pod, 1-2 rhinos
2 devastator squads, probably 1 plasma cannon based and 1 missile launcher based
Dreadnought (the siege dreadnought seems pretty cool) in fancy drop pod
Some sort of flyer (fluff says they take good care of their thunderhawks and flyers. Leading candidates are the rumored white dwarf one, storm eagle, assault ram)
Hopefully about 2000 points all said and done. Many of the details will have to be figured out once the rules for 6th edition appear.
