The Turkish company Yavascalar (YAVEX) developed the Eagle Eye Anti Riot Drone, which was promoted at Eurosatory 2016, Paris, France in June 2016. According to company marketing materials, it has an effective operating range of 5km2 and a maximum operative altitude of 3,000 feet. It weighs 5.4kg and can carry a payload of up to 5.5kg. It is fitted with an RCA projectile delivery mechanism which can release nine Yavex CS smoke projectiles which drop in free fall onto the target crowd below.363 According to MSI, the Turkish Defence Review Magazine, Eagle Eye can be effective over an area of 700-800 square metres with the projectiles it carries, depending on environmental conditions.364 The project has currently been suspended following the acquisition of Yavascalar by the Turkish company, Sarsilmaz.365 Certain “wide area” RCA delivery mechanisms may have utility in large scale public order situations in extremely limited circumstances; however they could readily be misused for collective ill treatment or punishment of crowds and their trade and use needs to be strictly controlled. Other “wide area” RCA delivery mechanisms such as RCA artillery or mortar shells and cluster munitions are inherently inappropriate for law enforcement. Research by the Omega Research Foundation and Bradford University has uncovered the previous manufacture and promotion of such weapons, including by companies in the Russian Federation, Serbia and Turkey.366 7.3. Recommendations  CoE member States should stringently control the development, production, stockpiling, import, export and other transfer of all riot control agents and delivery mechanisms in their territories in accordance with the Chemical Weapons Convention, and where applicable the Wassenaar Arrangement, the EU Common Position and EC Regulation 1236/2005 . In addition all CoE member States should ensure that RCAs and related delivery devices are not transferred to any end users who will employ them for torture, ill-treatment or other human rights violations.  CoE member States should ensure that all use of RCAs and associated delivery mechanisms by law enforcement and prison officers is in accordance with regional and international human rights standards. RCA grenades, launched cartridges and any mass dissemination of RCAs (e.g. via large backpack or riot sprayers) should be prohibited in confined spaces. Targeted use of RCAs (e.g. via hand-held spray) should only be resorted to when strictly necessary, be proportionate and for the shortest possible time using the minimum amount of RCA necessary to reduce the level of violence and to re-establish control.  CoE member States should determine which if any “wide-area” RCA delivery mechanisms may be justifiable for use in extreme large-scale law enforcement situations. The use of any such permissible devices must be in strict conformity 363 Yavascalar (YAVEX) Product Catalogue, undated, distributed at Eurosatory 2016, pp.48-49.
