Thank you for the information and your question and I am sorry to read that your son is having a difficult time in his Command. I can't second guess what is going on, especially since I don't have all of the facts from all sides. However, I can say that if he is actually being hazed (I have provided the Navy
definition supplied by the Navy Inspector General's Office below) that is unlawful and violates a general order and can be prosecuted under the UCMJ.
You did have a good recommendation that he speak to the Command Chaplain. If the Chaplain is effective, then they will be able to help him resolve the situation and can speak to the Chain of Command on his behalf. Ultimately though, unless the Chaplain can help him resolve this, he will have to run a "request Mast" chit up his chain of command (COC) so that he can speak to the XO or CO about the hazing. The COC is responsible for investigating and stopping hazing. If, for some reason, he believes that his XO or CO are participating in the hazing, which I would be highly unusual, then he could either file a complaint with the Navy IG or his congressional representative. Those complaints though will be sent to the Command to respond to. In other words, there is no real way to avoid Command involvement in resolving this, although in the latter cases they will have to report to someone outside the Command as to what has happened and the resolution.
You can find out more about how hazing and how allegations are handled in the Navy, by going to: http://www.ig.navy.mil/complaints/Complaints%20%20%28Hazing%29.htm
Please let me know if you need any clarification. I would be glad to assist you further if I can.
What is Hazing?
Hazing is defined as any conduct whereby a military member or members, regardless of service or rank, without proper authority causes another military member or members, regardless of service or rank, to suffer or be exposed to any activity which is cruel, abusive, humiliating, oppressive, demeaning, or harmful. Soliciting or coercing another to perpetrate any such activity is also considered hazing. hazing need not be verbal or psychological in nature. Actual or implied consent to acts of hazing does not eliminate the culpability of the perpetrator.
