Certainly an interesting read. I see the US has not learn t from the USS Pueblo (AGER-2) report about the amounts of unnecessary documents and code keys carried.
They also had a similar problem because they were carrying keys for Crypto that was not only compromised to the N Vietnamese and thus the soviets but they had lots of it inc KY28s so could read the mail for potentially months. They got the kit when they overran a store containing lots of it,
Whilst at a St Mawgan we had a go at destroying some old kit with a fire axe and we were well up for it. But we soon found out even with a lump of concrete to work on and not an aircraft deck or equipment rack it was slow work and not particulary effective. Lots of damaged cases but many PCBs intact
The same time we tried burning a pile of old obsolete un-classified documents in a bin with the approved destruction equipment. (1 Jerry can of waste fuel and a box of matches) to see how effective it was. It took ages and also was not effective, lots of document pages could still be read after we raked out the ashes. This was an experiment to see how long it would take us to destroy 1 cabinets worth of documents and spare kit. The conclusion was It took longer that we were allowed and was wholly ineffective. I see nothing has really changed.
I see that vehicle denial has moved up a bit though. I was reading that the recommended denial process for specialised vehicles is grenades inside.
Now that would be fun to have a go at !
