NATO’S Allied Command Transformation has been very fortunate to again hold the NATO Lessons Learned (LL) Staff Officer Course at SWEDINT. With outstanding support from Allied Command Operations, the Joint Warfare Centre and the Joint Analysis Lessons Learned Centre, the fourth session ran from 15-19 March 2010. Over 100 students have attended the course, which is designed to prepare staff officers, with or without previous LL training or experience, to manage a LL capability for a NATO or National organization. The next course will be held 28 June - 2 July 2010.
