To which Charlie Troop do you refer? In my time, I served in 3 different Charlie Troops (plus 1 Alpha, 2 bravos, 2 deltas, 1 Echo and a Foxtrot).
I think at least two of the C Troops were nicknamed Charlies Angels (not very original).
Your right, there was only one L-Lockett in the the core. Are you still serving? I wasn't in C troop, I have a cock, although come to think of it that probably wouldn't count me out being a member. Left Herford around 98/99 to go to 1 Mech.
