Bots on the ground: an impending UGV revolution in military affairs?

There has been speculation for some time that unmanned ground vehicles (UGVs) are poised to revolutionize military land operations. These expectations have amplified with recent developments, not least the reported deployment and testing of Russian weaponized UGVs in Syria. Yet when it comes to the operational use of mobile ground-based robots–armed or otherwise–the recent history of the technology can be described as one of promise so far unfulfilled. By tracing past and present efforts to develop and field UGVs–and the enduring challenges that lie therein–this article attempts to gauge the likely impact of such systems in future conflict, as well as their effect on international security more broadly. The article concludes that although UGVs will almost certainly become a major–if not indispensable–feature of future military land operations, they will, similar to other promising militarily relevant technologies before them, continue to produce unrealistic expectations about their impending revolutionary effect.
