British Army Communications

*Still Under Construction*
It seems that once the Armed forces get there teeth into a communication system they stick with it through thick and thin. The fact that the Clansman system that was developed in the mid 1970's is still in service today speaks volumes. With the introduction of the new Bowman encrypted system, Clansman is now slowly becoming consigned to the skips (Literately). But when Clansman was introduced the British Army was still using Larkspur, and the latter was still in the Signal aide memoire's for 1983. In other Army publications, Larkspur is still mentioned in 1986 but I suspect this to be more of a Territorial Army Issue than Frontline.
Field Telephone systems:

secure way of communicating, with no jamming or interception unless the line is
