USAF Global Hawks fly reconnaissance missions for South American Countries

The USAF is working to make its RQ-4 Global Hawks available to its allies in Latin America and the Caribbean.
The RQ-4 is useful for finding drug fields and helping plan offensives against rebel groups.
The drones can also map rainforests threatened by illegal logging, survey damage after natural disasters and take part in other missions the Pentagon refers to as “defense support to civil authorities.”
It's not known how frequently Latin American countries have taken advantage of these offers and there aren't examples of actual RQ-4 missions.
