Adding Vehicle to faction

class CfgPatches
{
	class SAA
	{
		units[] = {};
		weapons[] = {};
		requiredVersion = 0.1;
		requiredAddons[] = {"Name of PBO where the vehicles you want to use are"};
	};
};

class CfgVehicles
{
	class Vehicle
	{
	 faction = "Your_Faction";
	 crew ="Classname of your soldier"; // I think you can specify multiple crew members using a comma , not too sure though
	 vehicleClass = "name of the vehicle class you want it under"; // If you're using a parent class from Vanilla it should already properly group the vehicle under Air, Armor ect.
	};
};

Adding different sub groups

class CfgVehicleClasses
{
	class SFG // Add this under vehicleclass = ""; of the desired unit
	{
		displayName = "SFGs";
	};
	class 75th_R
	{
		displayName = "75th Rangers";
	};
	class Delta
	{
		displayName = "Delta";
	};
};
