Let infantry sit on tanks as a mean of being transported. Allow Infatry to hipfire and defend tank while sitting on it. These will reward defensive points on Both sides.
Armored Transport vehicles. Include armored transport vehicles supporting up to 2-3 squads. This will allow infantry to rush point. Maybe some transport vehicles can act as mobile spawn points, if they find a way to not make that op.
Plane strafing; Plane pen strafing on infantry. Strafing barley does anything to infatry just tried it out, it needs more area of affect and stronger damage.
It would be cool to add some sort of radio system between planes in the sky that allows communication only with planes in the air. Maybe radio could communicate with planes through voice chat, and tanks as well. That could eliminate infantry spam and leave voice chat with anyone with a radio to communicate with tanks and planes.
Maybe add the ability to play on old timey radio music in planes.
Also we could add a map animation when pulling out a map, soldier brings up paper map then it shows the UI map on screen. But anyone using a map it will clearly show them holding a map from a third person view.
Also maybe we can add binoculars for pilots to use while in plane or some sort of aerial free view.
Paratrooper; Maybe Enlisted could add some sort of A.I paratrooper plane that paratrooper squads can spawn in and jump at while it rotates around the map. Paratrooper will not be subjected to out of boundary limits to an extent like normal infantry. Paratrooper battle map access will be substantially larger in order to flank from all sides and land behind enemy lines.
Player Plane / Tank Joining; add a system where players can join open tank seats or plane gunners by requesting to join if it player of the vehicle allows open seating.
