I&#x27;m not sure decoys are worth it really. Conventional explosive are cheap. Very cheap. You might as well stuff them into every &quot;thing&quot; you deploy.<p>It&#x27;s different with ICBM&#x27;s.<p>But yes, I think you have a point in that with COTS robot technology, it should be very cheap to produce swarms of simple missiles. If the adversary answers with &quot;military-grade&quot; countermeasures, he&#x27;d go bankrupt..
