Add actual customization to vehicles/soldiers.
VEHICLES
E.x you could maybe add add-on armor, like tracks, sandbags, logs, or even concrete!
Sandbag covered tank:
Concrete armor Stug III
This add on armor could be gotten by unlocking the vehicle modifier. The currently not unlockable squad upgrade.
You could chose the add on armor for different prices. The cost would be in silver orders for weapons.
Maybe even a machinegun shield as a modification
Band of brothers TV show:
There should be more cistomization like bushes, flags on top of tanks, backpacks, enemy helmets, guns, and maybe even let us write a short name of the tank on the barrel.
Let us add decals to vehicles too, maybe like a symbol on a tank, like a bear on a russian tank, a bomb/heart symbol on a german tank.
Ofcourse i wouldnt like this but these cosmetics could mostly be bought by gold.
Let us chose different paintjobs for our vehicles. You could also make some of them paid exclusives for really good camos.
SOLDIERS
Let us add different things to our soldiers.
E.x Grass/ leaves on helmets. Branches to our sniper uniforms.
Different helmet covers.
Different uniform camo, but this would be expensive since you would have to purchase it for entiere squad.
You could purchase different ammo pouches/ maybe even have belts of bullets on gunners as decorations.
There are many more things, and i hope other people could come up with more things.
