Hi,
Interesting article here from today's BBC website:

I could see how the cutting holes into the armour panel being one of those counter-intuitive ideas that really work - my first thought looking at it was that it reminded me of those sand channels used on ATVs. The actual development of Super Bainite is pretty cool too - it just shows how materials that have been around for a 100 years or more can still be developed and improved.
