Are we really now in the realms of defining our future doctrine based on the ability of the title of the project/programme or study to form a clever acronym??? I've just spotted this in the June JHC Newsletter: "Visual Ability & Manned Performance in Illumination Reduced Environments Guidance (VAMPIRE) . The conduct of war has changed. Previously limited by daylight, around the clock preparation and actual combat is now the norm. Although our technology can continue to operate in darkness and without ârestâ, humans are less able to perform in reduced illumination and sleep deprived environments. The guide has been designed to collate information on the major issues surrounding night operations from various sources, and advises commanders and authorizing officers how to identify the hazard, and manage the risk. " Is this the same as...Fighting at Night? (FAN! ) Many more (real ones) I'm sure...!
