Well, I got snookered into this off of Dakka. I've got a Praetorian army, but I'm not as extensivly converted as some of you guys. What I can field:
Two Command platoons (Valhallan Lts painted as captains, one w/ Fist, one with Power Weapon)
Anti-tank Squad (LCx3)
Mortar Squad
Fire-Support Squad (HBx3)
Lt w/ power Weapon, FlamerX4
3XSquad w/ Autocannon GL
Lt, Missile, PlasmaX2
3Xsquad w/ Missile, Plasma
Lt, Missile, PlasmaX2
3Xsquad w/ Missile, Plasma
Lt, Lascannon
3X squad w/ Lascannon, flamer
13 Tallarn Roughriders (they go with 2 small tallarn platoons)
I use Catachan conscripts
My tanks are all a khaki, washed brown/black/brown, with large red/yellow/red stripes on the sides of the tanks like British WWI tanks
I cut the tips off of meltaguns and use plasma pistol bits to make plasma guns
I use Mordians for Veterans and the occaisional fill in troop.
My troops are painted with Red Coats, Yellow piping, Khaki pants & Helmts, black belts, dark brown rifle stocks and a range of flesh tones from elven flesh to african.
My usual Doctrines are Iron Discipline, Close Order, Sharpshooting (For anti-tank squad), Rough Riders, Drop Troops
I've been playing the Praetorians for about 2 years now, and took them to the Detroit GT, where I finished middle of the pack, but IIRC I had the best record of IG. They've also taken Best Army and Overall at local RTTs.
