Mike,

I spent some time working in southern Colombia near the Ecuadorian border, between 2004 and 2007. The Joint Interagency Task Force - South do have three common FOLs, and one of them is FOL Manta. If you are able to find some POCs down there, or better at the USDI / SOUTHCOM, you'll be in good shape for Latin American affairs.

Joint Center for Operations Analysis might have some good reading as well.

Best regards,
Rach
