I like it so far. It's got a really cool Republic Commando feel to it. The future of the story could be pretty cool, as long as you handle it well.

Things to work on:

-Work on the personalities of each character. Their personalities are fine individually, but work on the relationship between the characters in the Squad and how their personalities work together.

-Make the characters want to stay together. Yes, they have to stay together, as that is how they are assigned. However, you need to give them a reason to work well together. Right now, it just sounds like they all hate each other. It's fine to have conflict, but on a deeper level, they need to have a reason to help each other out.

-The grammar needs a little touching up. A few misspellings, but nothing too bad.

Work on those few things, and I think you have the makings of a great story here!
