update_units

To add units into a group or remove them from it, use the command unit_group/update_units:

svc=unit_group/update_units&params={"itemId":<long>,
				    "units":[<long>]}

The required parameters are marked with an asterisk (*).

The units parameter must contain the IDs of both the units that have already been added and the ones you want to add. To remove a unit from the group, you must list the IDs of the units that should remain in the group.

If the request is executed successfully, the following result is returned:

{
	"u":[<long>]	/* array of unit IDs */	
}

Otherwise, an error code is returned.
