Being a veteran in another war during the '70's in Nambia (then South West Africa) and Angola with the South African National Defense Force as an 17 year old conscript, I can so relate to this book!
The author describes mundane things like C rations (we called them "rat packs") and these were as awful as he describes. I am sure we got the leftovers from the Vietnam stock after the war! We were permanently hungry from not being able to eat these things.
The continuous on/off adrenalin was absolutely exhausting whether you were in contact or not. After a contact you do a follow up only to find it was two enemy soldiers that held a full platoon busy for almost an hour.
As I was reading this, I could actually smell the webbing we used ( am sure this was `Vietnam era' kit),the extreme heat in Angola, the sweating etc. A lot of memories (tucked away) came rushing back, and I actually cried when his mate Dave was KIA.
Brilliantly written!!
