hmmm on the range partHX-2 has a range of 100-120km and packs a shaped anti-armor charge, making it ideal for mid range strikes vs Russian artillery and armored vehicles. It's Germany's answer to Russia's Lancet drone and has significantly more range.
Line of sight communication from the UAV operators with distance and height because an issue with signals with such ranges. However, that is not an issue if you use satellites to control the UAVs at greater distances.
