I had to change my old list a little bit on order to get the Sternguard in. I changed my tactical squad into Sternguard by dropping one MM Land Speeder and by changing my Reclusiarch for a Librarian.
HQ: XXX
Libby w/ Unleash Rage (goes with DC. I know I should have a Reclusiarch with the DC, but I had to shave off points. At least I get a psychic hood and rerolls past first turn of combat. Any suggestions on the other power?)
ELITES: 525
Priest (90): w/ Jump Pack and Power Weapon
Furioso Dreadnought (XXX): (could always switch to a DC dread instead)
Sternguard x9 (310): w/ Power Fist, 2 Combis, Rhino
TROOPS: 755
Assault Marine Squad x10 (225):w/ Power Weapon, 2 Meltaguns (goes with Priest)
Assault Marine Squad x10 (235): w/ Power Fist, 2 Meltaguns (stays near Priest if possible)
Death Company x8 (295): w/ Power Fist, 4 Power Weapons, Rhino
FAST ATTACK: 120
Land Speeders x2 w/ one Multi-melta each
That SHOULD be exactly 1500 points, let me know if I wrote something down wrong, after all this is all from memory.
