When we got to Tidworth in 89 we were surprised to see that they had Stillbrew armour on after so many years with Challenger. The answer to the question "what the fook is that?" was answered with the army bought two T72's from the old East Germany and took one of the up to Kirtkubright. They fired an APDS or fin round at the thing and it went through with no probs. The other one shot at a Cheify turret and it went throught the mantlet. Some geezer called Stillbrew had a cunning plan and said we can put extra armour on and designed the mod. It was approved and fitted within 6 months, is this true? One of the problems I had with this mod was that it 'Ovalised' the turret ring. This meant that the traverse gear box was put under a lof pressure and couldn't do it's job properly. You would be motoring along and the driver would stick left or right and the turret would stay in the same place. Not too much of a problem if you were on the plain but VERY dangerous if you were on the road. In the two years we were there I had two gear-box lifts in two years, this was only a case of taking the box off and fitting shims but has anyone else had the same problems with this mod?
