Iraqi army training.....
“Now, when the enemy approaches, first drop your weapons, then take off your uniform (you have likely soiled it anyway), and RUN as fast as you can away from the enemy”.
The video of the Iraqi army showed soldiers actually aiming their weapons as they fired them. The enemy was literally shooting from the hip.
Certainly, cowardice played a part in the Iraqi collapse. But I'll bet political and religious considerations played a big part as well.
Suppose you are an Iraqi soldier. And you are Sunni. You wouldn't have a whole lot of motivation to risk your life for the corrupt Shia government in Baghdad.
