When he is not on duty or on patrol, there is not much to do in his "down time". IOW, boredom is a factor. They were having fun hunting lizards for a while, until they found out that the poisonous scorpions like to hide out in the same holes. So that put a stop to the lizard hunts.:)
The time he has spent in Iraq has been interesting to him. It's the only time they get to see kids, and they (the kids) just coming running right up to them whenever they stop the convoy, asking for water & candy, mostly water though.
I hope you liked the the photos of the children that proud yank found
