They are spent and feeling more broken.
Even the "world's greatest athletes" couldn't take this much stress. John Wayne McCain ought to take up that challenge for more than just a photo-op day.
Fatigue cripples US army in Iraq
Peter Beaumont in Baghdad | Sunday August 12, 2007
Exhaustion and combat stress are besieging US troops in Iraq as they battle with a new type of warfare. Some even rely on Red Bull to get through the day. As desertions and absences increase, the military is struggling to cope with the crisis
Hanna and his men are not alone in being tired most of the time. A whole army is exhausted and worn out. You see the young soldiers washed up like driftwood at Baghdad's international airport, waiting to go on leave or returning to their units, sleeping on their body armour on floors and in the dust.
Where once the war in Iraq was defined in conversations with these men by untenable ideas - bringing democracy or defeating al-Qaeda - these days the war in Iraq is defined by different ways of expressing the idea of being weary. It is a theme that is endlessly reiterated as you travel around Iraq. 'The army is worn out. We are just keeping people in theatre who are exhausted,' says a soldier working for the US army public affairs office who is supposed to be telling me how well things have been going since the 'surge' in Baghdad began.
They are not supposed to talk like this. We are driving and another of the public affairs team adds bitterly: 'We should just be allowed to tell the media what is happening here. Let them know that people are worn out. So that their families know back home. But it's like we've become no more than numbers now.'
