Ok, so we know for sure that squads are going to be 4 people. They have a structured set up where there are 4 people in a squad, 5 squads (20 people) in a platoon, and 5 platoons (100 people) in a battalion.

That definitely limits some of the above squad suggestions. Unless you just want to combine two squads. After all it might be best to split your team up in sets of two squads each. That way if they come across a bigger force they'll have more of a chance to fight them off or wait for reins (reinforcements).

Also that would change it from having 20 little 4 man squads running around, to having 10 group of 8 running around, which may organize things a little better (in a good clan that may not be a problem, but in unorganized groups a little organization can help a lot)

For my single squad set up, I'd go with 2 enforcers, 1 avenger, 1 phantom.

I think a lot of people underestimate the enforcer. Yeah they're supposed to be the most heavily armored class, but that doesn't mean they're going to be slowly walking through a battle asking for you took shoot off their head. If you watch some gameplay videos, enforcers can still move pretty quick and can definitely cause some destruction with rockets and grenade launchers.

I'd have the avenger constantly keeping his eye on the phantom while participating with the frontal fighting but staying back a ways behind the enforcers.

And of course the phantom in the back, either behind the avenger, or maybe with the avenger so they can watch each others back.

As for a squad leader. I agree with I agree Xerthil, anyone who has the experience, or is good at making smart decisions on the fly should be squad leader. They can always watch the HP of their squad mates and decide that it's time to pull out.
