I disagree, these are perfect for heavy recon where you expect to make heavy, possibly existential (for both forces) contact with an enemy while they are delaying ambush/contact to maximize the conditions for damage.

In frontline high intensity combat the role of these isn’t to be robot infantry that somehow beats highly trained humans, it is to force Russians to make a choice. As a Russian do you settle for having the timing of an ambush thrown off by an annoying robot driving right through the optimum kill zone of overlapping fire and opening fire on it having given away your position and the overall tactical initiative without having even made contact with the actual Ukrainian infantry yet?

Do you just let the stupid robot keep driving through and hope it doesn’t spot you? What if the Ukrainian infantry hidden nearby spot some of your defenders and the robot turns and unloads a .50 cal on them before you can launch the ambush?

Do you abandon your position to remain hidden until you can create a chokepoint where the Ukrainian infantry the robot is supporting are exposed?

Do you just sit there and hope the robot doesn’t see you? What if it already has and instead of firing the operator decided to give your exact location to a mortar team and keep driving as if they never saw you?

This is why a robot like this is useful in frontline contexts, heavy reconnaisance and making contact with an extremely entrenched and camoflaged enemy is a brutal job and infantry doesn’t tend to live that long doing it as a lot of the time no matter how careful they are, the enemy will hold fire if they are smart until the exact moment reconnaisance stands no chance of surviving contact.

Well, when it is a robot, who really cares if it survives contact or not? What matters is there wasn’t some human being out front who dies immediately and stood zero chance of being able to respond in time.
