The Naval Special Warfare community is deeply saddened and mourns the tragic loss of one of our own.  

Lt. Mark Weiss, assigned to Special Boat Team 12, Navy Special Warfare Group 4, died during an off-duty diving-related incident in Zanzibar, an island off the coast of Tanzania, Nov. 11.

Weiss and a fellow service member were on post-deployment leave to Zanzibar. The other service member was injured and is receiving medical treatment.

Our thoughts and deepest sympathies go out to their families during this difficult time.
