I keep running across these container objects that are misc items. I have a salvaged supply crate (was a footlocker I think somewhere in Scorpion Alley), a supply crate, and a radiated supply crate (both found in Bitter Springs).

They are all marked as quest items; anyone know what quest they are for?

The only one that I can find in GECK is "Radioactive Supply Cache", I can't find the other objects you speak of (unless you give their exact name).

I remember that in one quest you needed to get suplies in a form of cases , but i cant really remember for who it was ...

Ah, yeah. No, Not Much was for the ones I found around Bitter-Springs; but I still have that salvaged supply crate I found... I think in Fiends or Khan territory.

It's called "Disassembled Weapons Shipment."

"How Little We Know"

The weapons shipment is given to Torike (or something like that) if you side with Big Sal's plan to attack The Strip.
