Grid-based manual cipher system - this page is a stub

BATCO is a paper-based hand-held manual cipher system, introduced in the British Army in the early 1980s as a replacement for the ageing SLIDEX system that had been in used since WWII. The system consists of a set of vocabulary cards and cipher sheets for superencipherment of numeric code words. BATCO is short for Battle Code and was in use as a backup system until 2016, not only in the British Army, but also by the Armies of other NATO countries such as the Netherlands.
