To address some of the problems with land-mines (see ), weapons manufacturers are now experimenting with area-denial weapons which need human command to operate. Such systems are usually envisioned as a combination of either explosives, pre-targeted artillery shelling or smartguns with remote sensing equipment (sound, vibration, sight/thermal). By not posing a long-term risk, and by having some level of IFF capability (automatic or human-decision-based), these systems aim to achieve compliance with the Ottawa Treaty, as for example the Metal Storm ADWS (Area Denial Weapons System).
