Forces sweetheart

Forces Sweetheart (or Forces' Sweetheart) is an accolade in the United Kingdom given to those who have become a favourite of serving men in the British Armed Forces, though the term is also used in other countries.
Origins.
The role of being a favourite among the armed forces started in World War I. During this time, Lady Angela Forbes was considered a Forces Sweetheart as a catering organiser for the British army from November 1914. The British Soldiers' Buffets, commonly known as Angelinas, met every train of wounded as it arrived and were often open 24 hours a day, and food never ran out. Following her, Elsie Janis was called The Sweetheart of the American Expeditionary Forces.
