BTW one reason they haven’t deployed it before is you never show your full tech to the enemy until necessary. If you do, the enemy starts working on counters.
Look up the history of how we cracked the Enigma Code in WWII — and then used that tech sparingly — for an example.
But well now it’s necessary.
Th real test could come in a couple of ways, if Hezbollah starts firing ballistic missiles from Lebanon into the middle of Israel or Iran fires missiles from inside Syria or Iran at Israel, if you shoot them down with a Laser it would shock everyone, especially if it took out a missile at high altitude.
