Yes, I heard it's getting more militant too. One of the reasons for that is that before they were drafting from the poor regions and there a little money gives a lot of motivation. Not the case in better off regions, so force is needed to "motivate".

Poor or rich, it doesn't matter. They go to war and are ok with that as long as they're winning. There's no remorse or suspicion that they might be on the wrong side. They just don't care.
