Officer and therapy

My husband has been in the army for about 4 years now, he is an officer. His family has a history of alcoholism and we’ve discussed recently how I think he’s on his way for his drinking to really become a problem. I say that and I know 100% it is a problem. When he drinks he just becomes so emotional sometimes angry. He’s never been physical but I do worry it may eventually lead to that.

He said as officer it’s not available to get help and it ruins their career. Does anyone have insight to this?
