The Brewster Buffalo was arguably the worst airplane ever in American Military Service, hated by all who flew it, and despised by every ground crew who tried to keep it in the air.  It didn't take the Navy long to get tired of them when, they did what they always did when they wouldn't use some equipment:  they gave the Buffaloes to the Marines.

Many were exported to the Finns, who used them to good effect against the Russians.  The Brits also bought many of the Buffaloes.  Most were sent to Singapore, where they lasted about 30 minutes against the Japanese.
