(1) Out of two hundred or so rockets shot "at" your city, how many were on a trajectory that they'd actually have landed "in" your city? Not many because they're so wildly inaccurate? Or most because your city is large?
When someone is shooting at you with a rifle, do you not take cover if the bullet will not hit you? How would you even know that the bullet will not hit you?
When a rocket is launched, seconds count. All population centers in the direction of the rocket's travel are warned by alarm. That means that we grab our children and run, no matter if we are working, eating, shitting, sleeping, or anything else.
The nature of this particular question seems very naive. I suppose that you haven't been shot at much!
(2) You mentioned 200 hundred rockets shot at your city. Is this the sum of the tallies of "two different kinds of boom" you mentioned, or does the number come from a different source?
The number comes from a few sources. The army says this many have been shot, the citizen guard says another number, Hamas says another number, we count another number, the neighbours count another number. You'll never get an exact count, but they are all within a few tens of percent from each other. Interestingly, the Hamas numbers seem to be the highest.
Is the low casualty rate better explained by a high intercept rate by Iron Dome? Or by the inaccuracy of the rockets coupled with the fact that statistically a high proportion of possible landing targets wouldn't hurt someone? Or by the fact that so many people in your city sensibly seek shelter? Or by the fact that the rockets are fairly rudimentary and don't pack much explosive and are unlikely to do damage unless they randomly score a hit almost on top of someone? I suspect that the other factors are dominant and the low casualty rate is therefore not a good guide to the effectiveness of Iron Dome.
The low casualty rate is undoubtedly due to the fact that so many people sensibly seek shelter. The high COP of the missiles mean nothing when shooting at civilians, and they do have between 40 - 90 KG of HE, with lots of nasty shrapnel. These are not the pop rockets that were being shot ten years ago. These are Iranian and Soviet designed weapons.
The Iron Dome is a factor for the low damage, but the alarms are what is saving lives. Excellent question!
If by sound you distinguish an IronDome hit from a rocket that hits the ground, do you assume that all "ground" hits land in your city?
We can tell by how bad the building shakes and how much damage was done (i.e. broken windows, which we have had at my house).
In your tallies, you said you heard 4-5 rockets hit the ground. How many did you hear intercepted by Iron Dome?
I'll ask my daughters for their current count next time the alarms go off. I'm pretty sure that they are both well above 150 by now. Each volley is a few rockets (6-12), and we've had between 4-8 volleys per day for the past week.
Do you think the range of your hearing hit-the-ground and hit-by-IronDome are equivalent?
I really doubt it. The Iron Dome intercepts are in the air and relatively far from the city, thus they are harder to hear. Plus, they have far less HE than do the rockets they are intercepting. I suppose that we may be under heavier fire than I've thought. I'm not sure that is a perspective that I wanted!
