I probably should have done this from the beginning, but anyway, here's something to help visualize the soldiers of Omicron Squadron. Of course, if you're already imagining them in a certain way, then just go with that.

Sergeant Regis

For the leader of Omicron Squadron, we have these bearded but no less handsome fellows.

Vasili

I think the sniper of Omicron Squadron is best represented by a young Harry Dean Stanton. He's no supersoldier, and has a haggard, hangdog look that really captures Vasili's pessimistic yet heartfelt view on life.

Sindo

Even though I said the pilot of Omicron Squadron has curly hair, I can't imagine anyone embodying her tough beauty but Antje Traue, as seen in Pandorum (underrated movie). She's like gravel worn smooth by the pressures of life.

Birdy

Omicron Squadron's point man is a perfect storm of warrior genetics. I thought about going with pics of Captain America, but then again, Birdy's attitude is tempered by an understanding that he lives in a galaxy where most of the inhabitants see him as a threat or a resource to be exploited, so he has a sort of grim, bleak outlook that Steve Rogers doesn't necessarily embody due to his 1950s American heartland vibe.
