From the SarcasticGamer.com article: "Welcome to the sixth in a series of guides for the different starting classes in Mass Effect 2! If you enjoy this guide, please check out our other Survival Guides.
So, you want to be a soldier? Well, the good news is that despite some limitations you are probably picking the easiest class to understand and play with in Mass Effect 2. Unlike the first game where it was not advisable to play as a soldier on your first play through, picking the soldier class in Mass Effect 2 will have you running and gunning around the galaxy like an intergalactic badass in no time at all."
