"...These not only enable commanders down to section level and below to to establish exactly where they are to within a metre, but also allow superiors in the chain of command to ascertain the location of those under their command on a minute-by-minute basis without cluttering the net with messages asking ‘where are you’. The manpack radios in 1982 were not secure, so messages were of necessity terse. The only encryption system available at battalion level and below was Slidex, a Second World War vintage code. The slightest error encrypting a message produced the most amazing nonsense. It was difficult enough to use in quieter moments in a command post where at least some lighting was available in which to set sliding cursors and read off letters from a card when encoding or decoding messages..." — Matt Crypto 21:05, 17 January 2007 (UTC)
