Does he like being in Kuwait? My friends in the service who were there said they did--they were well received there by the residents and the society is relatively westernized.
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.
