well bro if he has a famiy and people that care about him then they should be doing something. Maybe there us a military recruiting office or military outpost that you can contact see if they have any programs or ideas. But it is hard to get someone help when they aren't interested in getting any help themselves. JThis a hard one to answer bro, but I think that it's admirable you're a caring guy like that. Maybe if you just confront him about his drinking and show him what you're seeing he might get another perspective. Keep me updated.
