1. POST CONTEXT AND RESPONSIBILITIES

The mission of the STO is to help position the Nations and NATO Bodies’ S&T investments as a strategic enabler of the knowledge and technical advantage supporting the defence and security posture of Allies and partner Nations. As described in the STO Charter, the STO Collaboration Support Office (CSO) is one of the three Executive Bodies of the STO.
Within the framework of the STO Collaborative business model, the CSO provides executive and administrative support to the S&T activities conducted through the nine STO Scientific and Technical Committees (STCs). The CSO facilitates the world’s largest and most vibrant scientific network for defence and security. More than 6 000 scientists and engineers from NATO and Partner Nations are engaged in approximately 460 carefully selected S&T Activities in the Collaborative Programme of Work (CPoW). Together, they work to solve real-world problems that Nations face today, and to better prepare their Armed Forces to meet future challenges. In its areas of expertise, the CSO provides assistance and support to the NATO Science and Technology Board (STB), its Chair, the Chief Scientist, and his/her office.
