You can only have so many strong silent types who observe everything. Also I think we already have a Tactical specialist haha. Though I like the Angle of a Pilot, we don't have anything like equipment Operators, some one who can pretty much get in the seat of something and drive. So could make like an Equipment operator. Some one who knows how to Fly/drive anything we might need. Would also recommend another specialization as well. Have to remember these people need to stand out from the rest. That's just my two cents.
