Earlier quoted context omitted.
A 10% success chance seems incredibly effective. I would have estimated the chances quite a bit lower. Tanks are million dollar devices, which are expensive to replace and require significant training. If they can be effectively attacked by infantry without putting themselves in significant danger, that drastically lowers the value of a tank.
We had man-portable ATGMs for decades, they didn't "lower the value of a tank". Less than 10% is not good when you consider how much does it cost in practice. Drone teams are often 2 pilots + technician + explosives technician (an incredibly risky job btw, those bastardised RPG warheads are live and sensitive) + infantry cover. At least double that if you want to strike beyond line of sight and need a retransmitter d…
Of course they did, arguing anything else is complete lunacy, especially since you later advocate for the usage of Javelins, which, if effective and available, obviously reduce the value of tank. They also have the imense drawback of exposing the soldier to enemy fire.
I don't even get your other points. Why would drone operators be hunted more than Javelin operators? Why would Javelin operators not have to worry about giving away their position? Why don't Javelin operators need infantry cover?
