During the exercise, explosive ordnance disposal and medical professionals were evaluated and certified on a series of tasks as part of Incirlik AB’s formal adoption of TCCC. This training provides early, life-sustaining medical care to wounded personnel and limits further causalities in order to achieve mission success. There are three phases of TCCC, which are care under fire, tactical field care and tactical evacuation care. TCCC was established by the U.S. Special Operations Command in 2002 and is now the accepted battlefield prehospital care.

12月1日，在圣地亚哥的通用动力国家钢铁和造船公司（GD-NASSCO）的一个小型仪式上，第五远征海军基地（ESB）即未来的美国海军罗伯特·E·西曼尼克号（ESB 7）开始建造。ESB舰级具有高度灵活性，可用于支持多个作战阶段的广泛军事行动，类似于远征转运坞级。作为一个移动海上基地，它们是关键接入基础设施的一部分，支持部署部队和补给，以提供灵活分配的预先部署装备和维持。

Construction started on the fifth Expeditionary Sea Base (ESB), the future USS Robert E. Simanek (ESB 7), at General Dynamics National Steel and Shipbuilding Company (GD-NASSCO) in San Diego during a small ceremony, Dec. 1. The ESB ship class is highly flexible and used across a broad range of military operations supporting multiple operational phases, similar to the Expeditionary Transfer Dock class. Acting as a mobile sea base, they are part of the critical access infrastructure that supports the deployment of forces and supplies to provide prepositioned equipment and sustainment with flexible distribution.
