WH - are you on any Milnet legacy system (CHOTS, LAND CSSR, et al)? If so and you can get on the Army intrnet site, it is there under JSPs. Hope it helps. If you don't have a system that allows intranet then you are fooked.
Chris - you would have thought that those who do SC work for MoD a civilian contractors/companies would do so........... but no. There are unclassified bits of JSP 440 that have been made available - I had a link once but now lost it!!!
