I love this clip, it reminds me of the good old days when I used to drive these things! 
That’s chuffin’ marvellous, lol! I want a tank! I used to admire this nutter in Richmond as a kid who had an APC and would drive it through the centre, and my GOD, you have no idea how loud those things are until you see one up close and personal! Race bikes haven’t got anything on a 10 litre APC!
I used to drive these things in Germany (and a few tours of Kosovo) and can attest to the fact that they are incredibly loud! However, not as loud as the Chieftan tanks were, as they would literally deafen people when they were moving through the camp in first gear! I vividly remember being sat in the Squadron offices when one went past, with all the windows closed, and the cup of tea on my desk had ripples in it! It was like a mini earthquake! 
Not very subtle are they
I don’t think the words “subtle” and “tank” really go in the same sentence!
