Just knowing that these don’t shoot may be a huge advantage to infantry that are being advanced on by them, as it will probably make them far less hesitant to pop up and take the top of it with small arms fire. Seeing as they’re using it as a taxi with the infantry on top, a large volume of small arms fire is likely devastating to it: those metal sheets don’t look capable of stopping much, but seem to be intended primarily to make drones explode further away from the tank.
