I like all three of those pictures, but have a hard time seeing a normal human carrying around a heavy plasma or an autocannon not mounted on a tripod. It's just a funky visual.
The thing about creating a regiment from scratch is that you *can* create a group of soldiers who have the appearance, through stats and style, who can write in their background that these abilities came, in part, from their lifestyle as mining colonists.
The three basic choices from the book were meant as backups for people who didn't want to take the group-built one, and because they were the cookie-cutter versions, a sort of nudge by the GM to help convince people to be involved in the regimental creation process. It worked with about 70% success, I'd say.

I wanted to vote to Heavy Reconnaisance, but Rpol was down yesterday, not sure why my connection was good to other sites.
Yes, it was down for about an hour [at least] yesterday afternoon when I was having my late lunch. Bothers me as it's tough to get a break at work Monday or Friday.
