second, if a soldier is a gambling addict does this make him unfit to serve in the military anymore? we know that addiction no matter where can make someone illogical and make him do things that he would otherwise never do. i am aware that these machines can cure their boredom but is it the best hobby to provide for their brave soldiers? what do you think?
In some countries it is part of requirement to have a good credit balance, it's often checked to ensure that these personnel have enough money and wouldn't have to do something illegal. It might not be the best fun to catch in the field but these are people sacrificing for the good of the country, they have choices on what should keep them entertained.
Soldiers are also meant to be psychologically strong and that should be helpful resisting addiction, with the limited free time and much concentration, it will be difficult for any military personnel to catch gambling addiction.
