It's incredibly relevant to any vehicle the Israelis build. Literately they can truck the vehicle back to the factory from the frontline within hours. A vehicle used by an expeditionary force may have very limited ability to fix or repair various items and only limited stocks of parts. The Israelis can "tune" their vehicles to the terrain and threat they know that they will face. Countries like Canada, UK or a force like the USMC may not know where they be fighting next.
Which is completely irrelevant for the vehicle's design, or the structure of its support chain.
Keep in mind the maximum distance a Israel IFV is expected to operate in for the most part, is likley within 40km of the border.
And how do you think this translates to the design of the vehicle itself?
Because I don't see any way it does.
For an Israeli armored unit, the supply of parts and ability to recover, is not as immediate as you may think.
And for an expeditionary unit, the ability to maintain their vehicles is not necessarily as bad as you suggest.
Any Israeli armored unit, can be called to fight either in the sandy and empty plains of Sinai against Egypt (low probability), in the urban environment of Gaza (very high probability), the rocky and muddy fields of southern Syria (medium probability), or the very complex Lebanese terrain of mountains, narrow passages, and semi-urban towns (high probability).
Each of them offers different logistical challenges, and the IDF is only in early stages of developing solutions to properly supply its troops in all these settings.
But if the circumstances necessitate it, the IDF possesses the capability to conduct complex logistical operations over much longer ranges than merely 40km beyond its border.
Currently it is in the process of setting up at least 10 spearhead BCTs, and 3 SF BCTs.
A typical BCT is larger than a typical brigade.
If the largest brigade in the IDF has 5 battalions, then that would be the size of your typical BCT.
3 BCTs are going to have the capability to deploy much farther than the spearheading BCTs, and will be composed of various commando and paratrooper units.
Now back to the US. What you're talking about is only relevant for the USMC, not US Army.
The typical MEU has 4 tanks, 7 LAVs, and 14 AAVs, or in other words 4 tanks, 7 IFVs, and 14 APCs. That's a total of 25 AFVs that need support and maintenance.
They are further supported by 4 artillery guns.
To supply them, they have at their disposal:
Of course, the heavy lift helicopters may be needed to resupply the aerial assets with engines and munitions. But in total you have approximately a shit ton of logistical assets to provide for a not too large ground force.
That is, per capita, a whole lot more than the IDF can allocate to its own forces.
And of course, just like the IDF will be setting up FOBs during fighting, so will the USMC.
