The thread is about the current Iraq episode. which is also a world apart from the first gulf war, in which the American forces and a global coalition walked over Saddam's '4th largest military in the world'.
Iraq is asymmetrical fighting and the soldiers are expected to take a great deal of 'police work', one of the problems of the IDF in the Palestinian territories and coalition forces in Iraq is soldiers showing unprofessional mentality after they have been subject to an exhausting routine.
You make an excellent point, Caladan.
My son served in an infantry unit in Iraq for 21 months - and 18 of that 21 months was without a single day of leave or vacation. He was 19 when he got there.
His brigade subsequently had the highest casualty rate in the war. In fact, the casualty rate was so high that several top officers were severely disciplined after the tour of duty.
As a parent, every day of that 21 months was filled with tension. I was part of the notification chain. When a death or severe casualty occurred, and the family gossip chain went wild with fear, I had a group of parents to call in order to disperse accurate information and dispel rumors until the affected family could be notified with the correct information.
It was awful. THEN I talked with my son afterwards, and realized that the fear and tension I felt was miniscule to the level of tension he and his unit lived under for 21 months of their young lives.
The death (and maim) rate was not only very high - but it was so RANDOM that it began to really work on the troops. They could literally never relax - not even while sitting on the toilet (my son had some stories to tell about having to dive for cover with his pants around his ankles). My son worked on patrols and at checkpoints. He said there was not one single moment of any day that you could let your guard down.
He put a video recorder on his helmet one day and recorded a patrol they were making through a village street. You want to talk about eerie - even though I knew that nothing significant happened during that patrol, the tension from both the troops and the civilians was incredible. The fact that the camera turned in the direction my son was looking increased the affect. I could hear 30 minutes of the discussion between the troops. Though it was full of profanity (and actually sort of entertaining), you could sense their fear.
When people are under a great deal of stress, they often turn to inappropriate humor in order to defuse the tension. Emergency room doctors do this (calling burn victims "crispy critters" for example - a common practice) - we all do at some time or other. Another example is the uncontrollable urge to laugh during a funeral, which is another common occurance.
It's a coping mechanism. Anyone who's ever taken a Psych class ought to be able to recognize this.
Throw in exhaustion and boredom (it actually becomes boring patrolling a desert checkpoint at midnight, even though intellectually you know you could be killed at any second), and you have a volatile situation emotionally and mentally.
As for questioning orders, and comparing combat situations to police situations:
Police work and war are two different scenario. The war these soldiers are involved in is chock full of political situations and local elements that they cannot possibly sort through from their position. US soldiers are taught to respect that chain of command and, especially in a tense, crisis situation, they CANNOT question those orders. This isn't brainwashing - it's common sense. You can't have PFC Jones jumping up in the middle of a cross fire shouting, "Hey, wait a minute - We shouldn't even BE here! I refuse to fire one more shot! Let's talk about the political situation!"
However, soldiers are not expected to be mindless drones either. They can question practices, contest decisions, etc - but not on the battlefield or in the middle of an engagement. This endangers the lives of both soldiers and the civilian population.
