David Fletcher - Vanguard of Victory; The 79th Armoured division.
Another in the HMSO series, very good with clear descriptions of each 'Funny' deployed by Hobart and his men, from AVREs to rocket powered ARKs. Not quite sure why it now commands a highish price on the second-hand market as it's more of a high quality extended magazine article than a real in-depth study, still worth a read though.
Cheers,
Adam.
