"If you compare the Egyptian military and the Tunisian military, obviously these are two very different institutions from and organizational perspective, but also their understanding of their political role." Kevin Koehler says. "The Egyptian military sees itself as a political institution and has a history of this in their country, which is not true in the same extent for the Tunisian military."

On this week's podcast, Marc Lynch speaks with Kevin Koehler about the role of militaries in Middle East governments and how political scientists study Arab military. Koehler is an assistant professor at the department of political science at the American University in Cairo.

Koehler also speaks about his research interviewing the Syrian army deserters. "One of the main conclusions which came out of this is that the level of control and supervision— even in the context of the ongoing civil war— is extraordinary, relative to other militaries and what common sense explanations would suggest about what drives desertion and loyalty in the Syrian military." Koehler says. "It's much less about identity factors or sectarian factors and it's much more about the lack of trust."
