I was fortunate to be able to read a lot of the UN reports oout of Iraq, jack McGeorge was their weapons expert, he and I shared a number of projects over the years before his death. The only things I remember being classifed was the formulations and some manufacturing techniques. As for ordnance it was pretty much what everyone has seen, except for some bio stuff. I remember a long night of booze and war stories with him, we wre going through a load of files - what I remember ( and what I'll swear too) is there was plenty of written evidence about ord items going to Syria, plus enough evidence to show a bio program. the problem was , and I think jeff made the point, there were a lot of coutries that sold stuff to Iraq and even helped them. In the end the UN will not say with all their might that a bio weapon was present or stuff went to Syria becasue they did not have an full up loaded item physically in hand, or what they considered enough evidence about Syria - I have some of JAcks files on this, but the rest went away after his death. As soon as I feel alittle better I'll pull a list of countries I can ID and post it along with what they sold or did.
HEM was an explosive mfg or loading plant. The letters show up on various HE projectiles if I recall correctly
