I was wondering when this would be broached and assume the usual PPrune Beadwindow police will shortly swing into action with their usual penchant for suppressing open source material.
JPR is of course a capability we (the UK) don't field, it is also one that is pretty much mandatory for operations. It also needs to be on high readiness in a sensible position.
In this case (Libya) feet wet JPR is pretty much the only option, in other theatres it would, of course be of limited utility. The capability you mention is, of course, not the only show in town, but they are all in similar places.
It would be intersting to hear AOC 1 Gp's slant on JPR given his publicly stated view on CDG's contribution, given that those boys on that ship were the ones covering his guys at the time.
