Some background/explanation. This is my first army list, so I don't yet have a good feel for what opponents I may be facing or what sort of tactics I personally like to employ. My goal with this is to make use of the majority of my current models, while purchasing to fill some holes and get me some more flexibility. I currently have 25 tactical marines, 5 scouts w/o snipers, 5 assault marines, and a rhino. About the only thing I feel really set on is my command squad, running a chaplain with jetpack and power fist with 10 assault marines, the sergeant running lightning claws. I see a lot of synergy there, and the potential to bounce around and wreak havoc.
HQ
Chaplain with power fist, jump pack - 130
Troop
Tac Squad with 10 marines, flamer, ML - 170
Scout Squad with 9 scouts, 3 sniper, ML, camo cloaks, Sgt Telion - 194
Elite
Term squad with 10 Terminators
Fast Attack
Assault squad with 10 marines, plasma pistol x2, lightning claws x2 on sgt - 255
Heavy Support
Devastator squad with 10 marines, 2x ML, 2x Lascannon, sgt w/ combi flamer - 280
Total - 1449
This list leaves me 50 points to play with, tossing in some grenades, homing beacons, maybe a rhino. I also am not sold on Sgt Tellion, so that could free up another 50 points. With that 100 I could lose some weaponry for a dreadnought, or toss in a vanilla tactical squad. I feel like I'm losing a lot of punch by having no mechanized units currently.
Tactically, I can deploy and combat squad the scouts deep, and teleport in Terms if deep strike is available. My chaplain will be running amok with my assault troops, bouncing around in a support role to hold off close combat units. I think there is some flexibility here, but a real weakness against heavily armored foes. I have 4 MLs and a couple lascannons floating around, but I don't feel like that's enough. My initial though on my extra points is a rhino with a hunter killer to give me some punch against heavy armor enemies, or dropping Tellion for a razorback with lascannons and a hunter killer.
Any and all feedback is appreciated. As I stated, a lot of this isn't purchased yet, so I'm open to swapping things around. I'm also curious about upgrading my teminators. The assault cannon and cyclone missiles seem very expensive. I'm looking forward to feedback on the list, thoughts on the abilities I'll have, as well as any tactics that might work with this list. Thanks in advance.
