The contemporary military environment characterised by new technologies, advanced capabilities, novel knowledge and skills sets, and a increased participation of non-state actors is leading to a rapidly expanding, non-linear, multi-dimensional battle space. Military operations are becoming progressively more joint, multinational and interagency in nature.Military leaders have a mounting responsibility to teams and groups and their organisations to accomplish a variety of very diverse missions.Unquestionably, the landscape in which military leaders must operate has affected the competencies and training needed to be successful. The aim of this study was to explore the possible relationships between emotional intelligence(EI),psychological capital(PsyCap),sense of coherence(SOC) and leader success of junior officers in the South African National Defence Force(SANDF).A cultural diverse sample of 170 junior officers from the rank of Candidate officer(CO) to full Lieutenant(Lt) was drawn from the South African Military Academy(SAMA),Faculty of Military Science,Stellenbosch University.This book will empower leaders,academics,researchers,students and people who want to make a difference.
