You are correct.
You are wrong.
I was active duty, F-111E RAF Upper Heyford, when Ronald Raygun presented the 'Star Wars' or Strategic Defense Initiative missile defense. Most, including many scientists, laughed at him. But not the Soviets. Not because Raygun was of any scientific minded intellect, but because the Soviets knew well how far ahead was American scientific prowess compared to their own.
Fast forward to Iron Dome and Patriot.
I was not surprised when those systems proved themselves in combat. Of course, they were not %100 successful, but when each system reached %50 success rate, bullet to bullet interception was essentially complete.
Here is why you are wrong...And I will
NOT use any 'classified' info to prove you wrong...Just logic and common sense...
1. Farm field
2. Parking lot
3. Army HQ
4. Jet fuel depot
5. Hospital
Let us say I have 10 interceptor missiles.
Why would I assign 2 per? Why would I care if the enemy attack the farm field or the parking lot?
Now I have 10 interceptors for 3 sites or 3 per.
3. Army HQ
4. Jet fuel depot
5. Hospital
Of those three, which is the most important? Believe it or not, it is not the Army HQ. In peace time, all units have their own assigned plans and executables. All the HQ does is storage for paperwork. Combatant commanders have nothing to do with HQ.
4. Jet fuel depot
5. Hospital
So now I have 10 interceptors for two sites, or 5 per, for defense. Do you see the point here?
Make no mistake, the Israelis are using much more complex defense calculus for their Iron Dome system than what I presented above. Do not think that every time you saw a Hezbollah or Houthi missile landed on Israeli soil, it was a success. Each attacker was calculated on where it will land and the system responded according to whatever priority the Israeli commanders deemed appropriate. The system is not perfect, but good enough for the Israelis to bear any failure.
