From 4-8 June 2018 the C-IED Staff Officers Course (CSOC) 18.2 was conducted in the C-IED COE in Madrid. The course teaches the students the basics to work in a tactical/operational level HQ and become the commanders C-IED subject matter expert. This was the second of three iterations in 2018. In total seven colleagues from the C-IED COE attended the course and accomplished the requirement for a C-IED COE member to have completed the CSOC. 24 students completed the course successfully. Compared to the usual training audience of the CSOC, the training audience this iteration had more NCOs and younger attendees than normal with lower rank. Also two representatives from the Guardia Civil attended the course with less military experience. This made the learning curve for the ‘average’ student very high. Also it showed the necessity to implement a general briefing with the introduction of an operational HQ. This is planned for future courses. .
