In Haiti, the mulato elite speak French. All Haitians, however, speak Creole.

When I was there, I did not identify any US soldiers, not even 3rd SFG guys, -other than Haitian born Americans - who spoke Creole. The 3rd Group guys were trying to pick it up, however. The ICITAP folk who were training the police - I knew their chief, Rick Lang, from Panama - were Spanish speakers. The RCMP were all French speakers (at least bi-lingual) and their may have been Creole speakers among them since Quebec has a large number of Haitian immigrants. But, then, the RCMP are Canadian, not American...
