sorry if posted before, cud not find it anywhere.
Was thinking, maybe you can have infantry teams. like a small platoon that you can use to battle tanks.
Useless yes, but in certain circumstances, people can use them incase there are many ground vehicles in your base. And like you can simply out it as gunners.
1- Bazooka
2- grenade/C4
3-HMG for low flying planes
4-Repair/Water horse (to repair buildings and blow out fires)
Just an idea.
So incase all air and vehicle hangers are gone, you wont need a base for infantry so infantr can be used as a last ditch attempt to delay enemy succeeding.
maybe it can be made that they always spawm near supply lines
