Peace keeping missions (whether peace enforcement, peace building, peace making, or conflict prevention) are very different to the formatted hierarchy and organisation of set-piece, large-scale military missions which Western allies have been accustomed to over the past decade. Even the experiences of ISAF or Iraq are outliers rather than a standardised format replicable across peace keeping tasks. This is also evident in the C2 of these missions: often more complex, ambiguous, woolly, and confusing than most military officers will be accustomed to. And that’s without bringing in a strategic HQ structure that has fewer staff and less experience than Western counterparts. Ewan Lawson, associate fellow at RUSI, talks through what characterises PK missions: his one-word answer? Fragmentation.
