Ok you think ooh tanks are gonna ruin this. With the input of helicopters and RPGs, I think there should be humvees. They hold 3 people. 1 driver, 1 MG operator and 1 passenger. 2 on each team. A RPG can blow it up.
More guns: Yes I would like to see more guns and modern guns. I am bored of regular guns so I modded. Thats 1 fix but there should be like 6 classes to choose.
Gun swaps and ammo pick up: I think switching guns or picking up dead corpses ammo would make the game more realistic. It will also help people who run out of ammo.
Limited sprinting to make it more life like.
Secondary guns like a pistol to help when reloading or out of ammo to pull out a gun and keep shooting
.
I also think special groups like: Medics, support, rifleman, snipers and demolition groups. They will have unique things in c their classes for egxample: Support: MG, Rifleman: M4A1, Demolitions: C4 and Thermite
Smoke. Grenades: If your pinned down in a hot situation the smoke grenade would help by getting support.
Planes: Not for bombs or napalm but for airdrops near enemy lines. But with airdrops there would have to be para-chutes to glide down in.
Bigger teams and maps for vehicles, planes and helicopter use.
I am not making it like cod just better in my eyes.
