If you're ever unsure of an acronym, the Lexicon of Terms over in the Travelers Tent is a good place to check

Not really, it would just be too big a piece, it would be a total POOP. For a good brick built base design, ask Rybuger or check out my Paladin class hardskin on MOCpages. If you want something more minifig based, the the battle armorand the pauldrons from BF and use a Lego motorcycle helmet with a big space visor, then attach a flat 1x1 loop on side thing to the stud on the back, for a gun, make your own or use the BF coilgun.

I like SC too. On SC2, I'm SPACEMARINE and my number is 608, add me.

I just use the battle armor at the moment http://www.flickr.com/photos/25071763@N ... hotostream
But, I do admit, I wouldn't mind seeing new armor designed with the SCMarine in mind.
