Question : Combine data from two separate tables.fields into one Query field

I will attempt to clarify my Question Title.
Objective:  Create a query result that combines the contents of two tables.field into one query and one field.  (I might be making this harder then necessary)

Summary Example:
Access source Table.field = Leas.LeasID   
Access source Table.field = Leas1.LeasID 
My objective is to have a query with one field that contains the combined data from Leas.LeasID and Leas1.LeasID (in Query.LeasID).
Query.field = Query.LeasID   where Query.LeasID contains the data from both Leas.LeasID and Leas1.LeasID
I dont want a Query result with two fields Query.LeasID, Query.Leas1ID.

Detail:
Table.field Leas.LeasID    is an Access Linked Table (linked to System of Record MS-SQL DB)
Table.field Leas1.LeasID  is an Access Table; I wanted an exact replica of the MS-SQL table to hold preliminary data (prior to it being populated in the System of Record MS-SQL DB). I performed a Get External Data > Import the table and data from the MS-SQL table.  I deleted data, but kept the table structure.  I plan to populate the Leas1.LeasID with preliminary data; combine the two tables into one query for reporting actual and preliminary.

Answer : Combine data from two separate tables.fields into one Query field

It just doesn't like all the brackets:

SELECT LeasID
FROM
(SELECT LeasID FROM Leas)
UNION
(SELECT LeasID FROM Leas1)

Or

SELECT DISTINCT LeasID
FROM
(SELECT LeasID FROM Leas)
UNION
(SELECT LeasID FROM Leas1)

Depending on your requirements
