I've been building Ultramarines for a couple of years now, and like a lot of players, I didn't really have any rhyme or reason to what I was building - I wasn't building a particular list. I started the hobby with a handful of models that lars4life generously donated to me, then I picked up the Assault on Black Reach box, and after that... well, I just bought what I thought looked cool. (Not that there's anything wrong with this method - you should always enjoy what you're building. It's just not a particularly cost-effective way to approach the hobby, especially if having a competitive list is one of your goals).
Well, I finally got around to figuring out the points for my models and started looking towards list building, and I was short some Ultramarines - three, in fact. Given that tactical squads are a maximum of 10 marines each, and I had 27 tactical marines. I decided to remedy this, and went to my bits collection - unfortunately, I had no legs. I resigned myself to buying some legs from an eBay bits seller, and a few days later these arrived in the mail:
...then I grabbed my leftover marine sprues, and started chopping parts off:
I just threw them all into a bag (I was on my way out the door) along with a large bag of bits I bought at a convention a couple of years ago:
After fiddling around with some options, here is what I wound up with:
The un-helmeted marine will be the Sergeant, and the other two will be troops. I'm glad I had an extra "beakie" marine head, I like to mix those in to keep things interesting...
