I'm Dick (without an "a" in front of it please), I have just left the British army after 37 years in the RTR, having served on Ferret, Saladin, Chieftain, Scorpion, Challenger 1, Spartan, FV438, Striker, and Challenger 2. I also dabble in a little light authorship. At the moment I am particularly interested in Challenger 1 as I am writing the Haynes Manual book on it!
