I actually used to have that book ages ago, it's 'Panzer Commander' by Hans von Luck. Seen the channel before, they transcribe all those paperbacks that used to be everywhere, not so much anymore. First person accounts of the war, usually German. No accreditation though, which is a shame. Gets them out of paying the publisher I imagine.

Who didn't read 'Forgotten Soldier' by Guy Sajer? Or 'Soldat' by Siegfried Knappe.
