Thanks all, good info coming out of the woodwork ;-)
Here is a photo of an AEC armoured demolition vehicle, showing the pioneer tools (is that the British terminology?) neatly stowed on the rear:
shovel, pick, helve (note that it doesn not have steel bands!) and crowbar.
The vehicle in the photo is from contract T9291 covering Lorry 3ton Armd Personnel and Armd Demolition, 100 vehicles between the two types.
