The V-shpaed vehicle design has been around since the 1970's, first in Rhodesia and then developed in South Africa. The only open source book I know is Peter Stiff's 'Taming the landmine', which is now somewhat dated and is easy to find on Google.

Why the later South Africa versions have not been purchased or licensed by the coalition eludes me.

Yes, they were originally designed for 'bush warfare' where land lines were the main threat, not IEDs in urban areas. Are the principles of design and threat not the same?
