	Description:
	spawns VEMFr AI using given _pos and unit/group count. Handles their inventory and transfers them to a client

	Params:
	_this select 0: POSITION - where to spawn the units around
	_this select 1: SCALAR - how many groups to spawn
	_this select 2: SCALAR - how many units to put in each group
	_this select 3: SCALAR - AI mode
	_this select 4: STRING - exact config name of mission
	_this select 5: SCALAR - (optional) altitude to create units at
	_this select 6: SCALAR - (optional) spawn radius

	Returns:
	ARRAY with group(s)
