My argument is that countering this threat is non-trivial, there are no existing systems in the US that address this threat, and that simplistic solutions should be evaluated on their merits. It's far too easy to hand wave away the complexities of the drone threat. For example, say we deploy an Arena/Trophy type system around an airbase? What are the ROE for its use? Do we keep it operating 24/7 or only when the threat level seems high enough? Most airbases in the US have small security detachments, and they have ROE that tell them not to blow up semi trucks that might have stalled on a road near the fence. So how do they counter an attack like Ukraine just pulled off?
