Hello Alien old chap not seen you around for a while - good to see you back.
I was talking to a couple of jock armourers at the weekend who also had nothing but contempt for the chain gun, which was by all accounts hideously unreliable, in large part they felt due to the fact that it was designed to be fed from above (as it is in Warrior and Challenger?), but in Sabre was fed from below so the gun had to pull the rounds up, leading to regular stoppages.
