There are many,Farley Mowatt wrote three books on his war experiences. My Father's Son, The Regiment and And No Birds Sang. The Regiment is actually the regimental history of the Hasty Ps in WWII. All excellent reads but I like My Father's Son the most.
Also an excellent read is Battle Diary by Charlie Martin. This tells the story of the QOR in WWII including the landing on D-Day.
The Long Road Home by Fred Cederberg is also a well written and enjoyable account of his war in Italy.
More modern writings include Scapegoat by Kyle Brown, The Sharp End, Signifigant Incident, and Peacekeeper. I have heard rumours of a book called Eat Your Weakest Man about life in the Airborne but have yet to see it on any shelves.
