Personally, I dislike the way Ammo Dumps/Trucks work in the game. I don't think it's at all plausible, or realistic, and, in fact, it's the only part of the game I'd call twinkish.
Now, ammo crates are useful in certain scen's to simulate, for example, para's having to get to dropped weapons/ammo, and dumps and trucks make good objectives for scens, but the 'lets set up an ammo dump 200 meters from the front' is really very silly, IMO.
Of course, that said, nothing is more pleasant to sneak infantry up to that dump/arty concentration and wipe it all out :)
