Welcome to Librarium Online!
Kicking the idea around in my head of M.A.D.(Mutually Assured Destruction), and how it could be applied to the imperial guard, and came up with the following list... exactly 1500 points! Again this is just fun, I thought it was goofy enough that it may actually work =)
troop 1: infantry platoon
pcs x4 flamer chimera flamer / flamer
x2 infantry squads flamer
x2 special weapons squad x3 demo
troop 2: vets demolitions x3 flamer chimera ML / flamer
fast attack 1: vendetta hellfury missles
fast attack 2: vendetta hellfury missles
heavy 1: Deathstrike missle launcher
heavy 2: manticore
heavy 3: manticore
Yarrick will deploy with the 2 infantry squads (combined).
The special weapons squads will each get a ride in a vendetta. Hellfury missles (or hellstrike, can't remember which is which atm) because... after the first shot it probably won't matter! More templates and ignoring cover = good in this list.
The general idea is to inflict massive amounts of wounds randomly, and fratricide is a plus!
I think it may be a requirement to model a sergeant riding the deathstrike with a cowboy hat, rodeo style...
I can't say much for its effectiveness, but it sure looks like fun to play
