I also found it to be a high number of shells for one truck. If one weighs 100lbs (and I am sure they are more) that's 150,000 lbs, or 75 tons. Our tanks weigh around 60 tons, so I suppose it's possible to have that much ordnance in a large semi. If there are that many shells, do any of them contain sarin? That's the real question, since we know they've shown up there before.
That's what I was thinking, maybe 100 lbs. Plus container weight. Gotta be one big truck.
