Throughout the Summer, the US-built M142 HIMARS established itself as a symbol of Ukraine's ability to strike back against building Russian momentum, perhaps even edging out the Bayraktar TB2 as the meme weapon du jour in the heated social media war. While there's no denying that the HIMARS are having a measurable impact, UA artillery units have already been making use of a home-grown development that, in the long term, may make the biggest difference in the conflict's asymmetrical artillery duals. This is the GIS Arta targeting system, and the effects of its innovation may outlast that of any other tool seen in this conflict.
