Hi everyone,
(caveat: I'm a massive
40K newb - haven't played since 6th, and even then was only a couple of times. So I don't know the rules or "what I want the army to do", per se)

I'm also more hobbyist than gamer.
That said, I'd like to build a viable force!
I recently came into possession of a good sized Ultramarines army and want to expand on it.
So far it has (note: I realize some of these choices, like the basic land raider, aren't considered very good but I'm fine with that).
Land Raider, lascannons, multimelta
Predator with 4 lascannons
Rhino x 2
Razorback with lascannon
5 veterans (old school models - like very old - I can't really tell what they are supposed to be. looks like they have a flamer and bolters)
10 man
tac squad
10 man devastator squad with missile launchers
10 man scout squad, mixed weapons
10 terminators - looks like a regular type squad - missile launcher (I forget the name, on his back
lol), assault cannon.
Command squad with apothecary, champions
Dreadnought with multi-melta and fist
Special chars: Telion, Chronus
Captain
What I have already on hand to add
4 bikes, one grav gun
1 attack bike
1 land speeder with
MM
Sicarious
Plastic librarian in power armor
Storm Talon
Stalker
5 assault marines, 2 flamers 1 eviscerator 1 grav pistol, jump packs
I like plastic kits more than individual metal models/characters or finecast (which is why I'm hesitant to get a Thunderfire for example)
Any thoughts on other kids to add (maybe Sternguard?) to have a well-rounded force to choose lists from? I'm guessing a drop pod is probably a must....I hate assembling those
lol
I'd love any and all advice.
