I find it interesting because in modern world we see more and more integration of computers into soldier's gear. The next logical step would be a total integration of a aiming computer into weapon itself - first steps toward that apporach are already here with for instance FN-2000 rifle and many others. However, what further enhancement of the designs would probably become an addition to the so called Soldier 2000 battle systems, where soldier is already part of larger computer based system (command and control). So I'm not surprised I see camera here - ability to send images to officers directly could be a tactical advantage. Question remains if such computer screen mounted on weapon would be of primary or rather a secondary use. Honestly, I think there's room for both, but with modern progress of flexible, transparent displays I think we might see in a future helmets that would incorporate HUDs, IR vision, light enhancement and many more options, thus making the weapon based screens obsolete or for emergency use only. They would still need however to be designed with peripherials (camera, laser designator etc) that would be then bridged digitally with the rest of the gear.
