Well, I sat down just now and wrote a list solely based on Jump Troops
HQ- Dante: 225
Elites- Sanguinary Priests (3): 270- Jump Packs x 3, Power Weapon x 3
Troops- Sanguinary Guard (5): 250- Chapter Banner, Infernus Pistol, Power Fist
Troops- Assault Squad (10): 250- Power Fist, Infernus Pistol; 2 x Melta-gun
Troops- Assault Squad (10): 240- Power Weapon, Infernus Pistol; 2 x Melta-gun
Troops- Assault Squad (5): 135- Lightning Claw, Plasma Pistol; Flamer
Fast Attack- Veteran Assault Squad (5): 210- Lightning Claw x 2, Infernus Pistol x 2
Fast Attack- Veteran Assault Squad (5): 210- Lightning Claw x 2, Infernus Pistol x 2
Fast Attack- Veteran Assault Squad (5): 210- Lightning Claw x 2, Infernus Pistol x 2
Pts: 2000 KP: 11-13 Scoring Units: 4-6
So, the idea is to try and use descent to bring everything in at once. Bring in the Sanguinary Priests first, in any of the Troops Choices really. Then bring the Veterans down near them and try to get the Priests bonus for their Heroic Intervention. Each Vanguard squad should eliminate a squad the turn it lands. Don't pair the Lightning Claws. 2 Marines with 1 is better than 1 marine with 2.
If you can bring in 75% of the force at once, that is still 33 Marines in at once, ideally 15 of them Assaulting when they arrive. If you pull it off right and get furious charge then you should be Golden. And if you are near the Chapter Banner, you are really set.
Even without bonuses, a Vanguard Squad should get 6 Power Weapon Attacks that re-roll to wound and then 12 Normal SM attacks. 18 Attacks that can't be stopped from reaching the table is nothing to scoff at.
