A while ago I finished the bulk of my space marine refurbishing project. I had started a space marine army at the end of grade 12 (that's the year 2000, just so there isn't any confusion) and stupidly painted them as Salamanders. Codex Armageddon was new and it had a cool army list for the army. Like all things that reside on the fringes of GW's rules and army lists, the salamanders were no more and I was stuck with snot green painted models. Repainting began shortly after 5th edition came out.
Below are some of the odds and ends that I always ignored in past editions of space marines, but now appear to be pretty good.
Former tactical Terminators who have had their arms swapped out for TH/SS. The 3+ invulnerable is the main reason for this.
My future Britz have used the above Razorback for transport in the past, but I have something else for them to ride around in (once I get it painted) so I'm giving it to the marines. I also converted the turret to a lascannon/twin-linked plasmagun. Beside the Razorback is an alternate turret for my Predator. I have another Predator hull with lascannon sponsons, but it's too expensive points wise (maybe I'll paint it for the next edition).
Hopefully, I'll have pictures of a new Sternguard unit soon.
