Was the fault ever located? Symptoms were after a HESH shot fell short, an add correction was entered and the next shot fell shorter still, as if a drop correction had been entered. It affected a lot of the CR1 fleet but not all. I would suggest a substantial minority of the fleet was affected. I got posted from LAD to REME Bn whilst it was still being investigated and by the time I got back to First Line, CR2 was in service. I never thought to ask at the time if it was ever solved and it only springs to mind now four years after finishing my 22years. I do know that REME Artificer students at Arborfield were assigned to investigate it as a research project and were assigned range time and muniton. Was it ever solved? Before somebody pipes up why have I posted it here and not in the REME forum. I want to know if the tank crews ever received a satisfactory explanation for the problem and got it sorted.
