By DLA Distribution Public Affairs

                YOKOSUKA, Japan  –              
Navy Cdr. Allen Rivera relinquished command of Defense Logistics Agency Distribution Yokosuka, Japan, to Navy Cdr. Horacio “Jack” Tan, in a virtual ceremony held May 22.  

Navy Capt. Kristin Aquavella, commander, DLA Indo-Pacific, virtually officiated the ceremony from her command at Pearl Harbor, Hawaii. 

The virtual ceremony was conducted due to the current health threat posed by the worldwide pandemic COVID-19. Social distancing and travel restriction procedures in place prevent large gatherings. Therefore, virtual events are required for these types of formal ceremonies. 

Rivera distinguished himself by providing outstanding meritorious service as DDYJ’s Commander from March 2018 to May 2020. During this period, he made significant contributions to DLA and the warfighter while leading a diverse workforce of over 340 Japanese Nationals, 40 United States Civil Servants, and 30 Navy Sailors. Rivera displayed tremendous leadership in the management of 22 multi-commodity facilities in five geographical locations in Japan that included more than 52,000 line items of material valued at more than $326 million.

In her remarks, Aquavella praised Rivera’s accomplishments during his tenure as commander of DDYJ.

"A.J., you can get the warfighter what they need when they need it, with a 98% accuracy rate. DDYJ is a hard-working, high-performing team. You have successfully steered your organization to success."
