There’s “Tank Twins” by the Dyson brothers, Bryan Perret’s old “Churchill”, and, if you can get hold of it, John Foley’s utterly magnificent “Mailed Fist” (surely long overdue for republication). Although it is fiction, I would also recommend Foley’s “Death of a Regiment”.
There’s also ‘D-Day to Victory’ by Sgt Trevor Greenwood (C Sqn, 9 RTR, 31 Tk Bde), which is a war-diary rather than a memoir. I also see it in UK bookshops all the time at the moment. Very interesting for the worm’s-eye perspective of serviceability rates and personnel issues within a squadron, as well as the surprisingly high rate of German air-attacks.
