For starting out, that will be fine. I would skip link teams for the first few games. You'll have enough to learn as is. You may want to switch to one 2nd battalion Scots Guard and change the paramedic for a 112 doctor.
I would actually use something like this list

Since it has a bit of things you may want to get used to using right away, including smoke (the highlander) irregular and impetuous orders, and some camo.
You want to avoid an obvious lieutenant later on, but for now it will look to be one of the 2 volunteers. That's enough for starting.
