Two Navy divers, James Reyher and Ryan Harris, died in a diving accident at Aberdeen Proving Grounds in Maryland on February 26. They were assigned to Mobile Diving and Salvage Unit 2. Meanwhile, the Navy Seabees headquarters, First Naval Construction Division, began a realignment on March 1 to improve efficiency by merging with Navy Expeditionary Combat Command and eliminating an unnecessary headquarters layer. The realignment will consolidate Naval Construction Force command under two new Naval Construction Groups, one for the Pacific and one for the Atlantic.
