Target creature gets +2/+2 until end of turn. If you control an Equipment, create a 1/1 white Human Soldier creature token.
The Human Soldier token that you'll create can't be the target to get +2/+2.
You'll create a Human Soldier token if you control any Equipment, not just one attached to the target creature, or even to any creature at all.
You'll create only one token, no matter how many Equipment you control beyond the first.
