My stance on this issue of soldiers gambling in camp or barracks as it may be called is beginning to change. Especially on the fact that these soldiers will be gambling with their own money, bear the losses alone and not be able to claim the profits from winning. I have seen these gambling from the angle of entertainment for the soldiers, but now I am beginning to get a clearer picture of the whole situation...and yea you are right, that's stealing. But the soldiers still have the choice to make, if they want to gamble or not.
If the money generated from gaming soldiers is used to support their wards and family in the barracks or improve facilities and artilleries it won't considered a complete waste for the heads in charge of the business. The soldiers lose money directly while the military win indirectly. They could support themselves this way, if things get well organized and coordinated regarding the organisers. Also, the soldiers should be made aware of the harsh effect of addiction .
