Answer: What is American Ambulance Great Britain mean?

American Ambulance, Great Britain (AAGB) (sometimes wrongly referred to as the Anglo-American Ambulance Unit) was a humanitarian organisation founded in 1940 by a group of Americans living in London for the purpose of providing emergency vehicles and ambulance crews to the United Kingdom during World War II. The idea for the service came from Gilbert H. Carr during a meeting of the The American Society in London shortly after the Dunkirk evacuation.

Funding came from private donations, both from Americans expatriates living in the United Kingdom and from the United States and the organisation was headed by Wallace B. Phillips (Joseph P. Kennedy, then United States Ambassador to the United Kingdom, was Honorary Chairman). Within six weeks of being set up £140,000 had been raised. By the end of 1940 the organisation had raised $856,000.

American Ambulance, Great Britain eventually operated a fleet of around 300 vehicles.
