Basically if people are given the realistic amounts of Ammunition instead of shoving crates everywhere (though in some places that is realistic) you have proper logistical vehicles
like Chinhooks could drop of BF:V style crates or something
But the real Meat of this Idea is having a Flatbed Truck (or equelevant) which not only re-arms and (maybe) heals people but Is laden with Kits (sort of like a mobile armoury) so when the defence of a point goes sour players can swap their kits for something more appropriate instead of just having to die
it could also feature deployable .50's and other defensive weaponery so after capturing a point a team can bring up the flatbed and realy get their teeth into defending it!
