To get a turret spotter to appear on a vehicle you will need:
1. The binocular and turret_spotter lines within the ABP.
2. A vehicle that is actually rigged to hold a turret spotter.
3. Add the turret spotter within the ebps/crew_ext and enable.
I believe the Churchill can already have a turret spotter in vanilla so look at what the devs did there.
Add this into the Stug ABP and the required hardpoints and actions to enable it.
