Being able to call in artillery or use mortars would be awesome. Things like smoke barrages would really help your tanks and teammates to push into an objective. Needed Mortar fire support could be marked by a device would awesome as it would tell mortars to fire on a specific location. On top of this binoculars would be useful so they could spot them, line it up, then fire. Multiple types of mortar shells would be awesome as well such as cluster thats would be wide spread but inaccurate, and a single basic one that was small in spread but a lot more damaging and accurate. I can’t think of much more. Thank you!
