Having ammo trucks in your core is a matter of personal preference, I guess. Since core elements can be added (if you have repair points) and deleted whenever you want, it's not like you are stuck with what you pick at the beginning of a campaign. For me, I prefer a couple in the core so it's one less element to worry about taking out of support points. As with just regular trucks, ammo trucks can be upgraded to armored ammo carriers at a later point and some of those are armed. And while you are correct that experienced ammo trucks don't deliver resupply any faster, their experience might be the difference between being just pinned by nearby artillery and retreating or even worse, routed. Experience will also allow a better chance of rallying. Seeing my less experienced, yet cheaper ammo truck retreat three turns before I get it under control could mean units needing resupply have to wait six turns.

While I mentioned, I don't like trucks as transports because they are too easy to kill. Still experienced transports, be they trucks or tracks, will suffer less suppression to incoming fire, just like ammo trucks. They are also easier to rally as well. As an added bonus, units in them are also rallied. Higher experience of the transport also benefits the transported. Also, if the truck is less experienced, like the ammo truck example, it could go running away. You've got your 65exp truck running away with your 100exp SS infantry unit! A 100exp truck has a better chance of getting your 100exp SS infantry unit where it needs to go faster. How much faster? I don't know because I would never keep a truck in my core without upgrade long enough for it to get to 100exp. I'm just trying to point out they are not a complete waste of space.

A good argument could be made for not having transports in the core at all, whether they are trucks or half-tracks. They are nearly useless on a defend mission. I've had the AI assault with 100+ tubes of artillery. My infantry hunkers down in bunkers for protection, but unfortunately there aren't underground parking garages for the transports. I usually leave them parked on the back edge and hope the don't attract attention. If they aren't part of your core, however, you could end up spending a lot of support points on transports for other battles. My core has two SS infantry companies with 14 half-tracks each. That's over 500 support points if they weren't part of my core. For that reason, they are in my core and they do set out of harms way during defend missions.

I do understand the point you are making. You want your experienced core to be composed of units with some offensive or defensive capability. I'm just trying to point out that there are some advantages to having experienced non-combatants. If there were more limitations on changes that could be made in your core, I think it would matter more. It matters more early on before you stock pile some repair points so you can add to your core. Beyond that, I think it's just personal taste.
