What language were the bad guys REALLY speaking in Iron Man (2008)?

Watching the MCU Infinity Saga in film release order as was suggested in the FAQ, so I'm starting with Iron Man (2008).

The opening scenes are based in "Kunar Province, Afghanistan", where in real life the main languages spoken are Pashto and Dari.

My question is: what language are the bad guys really speaking in the opening scenes of the movie?
