Okay people I am not talking about "Precision" in terms of accuracy here but it terms of collateral damage. Unless the stockpile was comically piled up in the sandbox outside of the school the tanks would very likely have to shoot through something to destroy them.
A disposal team on the other hand may be able to enter the building and defuse/disarm the weapons. (After its properly cleared by IDF forces for traps and enemy combatants.) Remember folks in her own article these sites were listed as "Vacant" so its a pretty safe assumption there weren't any people inside, furthermore if there were, given the fact that these sites were known to be vacant proper presumptions could be made about anyone who was inside.
Let's start from the end.
Disposal team disarming each weapon, at a site distant from the building where the cache is - ignore everything surrounding it. It can be a building in Canada or Iceland. Consider the time involved in doing just that action.
Add time for possible traps/IEDs that must be disarmed before proceeding with disarming and moving the actual weapons.
Now, add significant security detail - IDF forces surrounding the school and corridor by which the defused weapons are exfiltrated for further disposal (since the requirement is to not damage the building in which it is cached).
Lastly, the IDF forces are now in a fixed position for X amount of time to protect the operation. The IDF may take sniper fire, possibly returning fire, to include tank fire into the building from which they are being sniped. They may be engaged by hit-and-run attackers. They are however now fixed in place to protect the disarming operation.
It was likely better to accept the collateral damage to the building to dispose of the munitions in-place versus the potential pitched battle to disarm and exfiltrate the munitions.
Also, I know a lot less about air power than ground weapons, but I was under the impression that the accuracy of a JDAM was about five meters. Which is really really good, but still, not anywhere close to a main tank gun.
That impression is accurate to keep things simple - a lot goes into how accurate a GPS fix can be from the number of satellites in view, their position, how cloudy it is, whether it is solar min or max, etc. The type of receiver also matters (even on the civil side, a
surveying receiver vs a smartphone have different error margins).
LGB's are a different story entirely. (
