I would posit that making some AI-controlled weaponry on par with humans at target identification/recognition is not too hard, and definitely doable with today's tech. Making one that's _better_ than humans though, that's the tricky part. Another issue is full autonomy: even human soldiers/pilots/etc. are not fully autonomous - they will ask command if there are civilians or friendly units in the AO, as they don't always have enough information to make that decision themselves. To achieve that with machines (not necessarily AI), you either need a fully integrated system (i.e. humans are obsolete for military use), or you need an efficient and functional human-machine interface. So I don't expect we'll be seeing fully autonomous AI weaponry anytime soon, despite it being technologically possible. AI-_assisted_ weaponry, however, probably already exists.
