Above All, Courage by Max Arthur, first published in the 1980s.
Broken up into several short interviews with British personnel in the Falklands War - Navy, Marines, Army, Air Force, etc.
Lots of different trades: chaplains, medics, pilots, sailors, infantry, even some civilians, if I recall? Ranks range from squaddies up to admiral, providing a lot of persepective - very, very good stuff.
It's not Falklands specific knowledge, it's not so much about tactics and strategies, more focued on the personal elements of what happens during a campaign.
Read it 20 years ago, and some quotes stay with me to this day.
I remember the Brit chaplain being asked how he could tell who would fight bravely in combat, and who wouldn't. He said there was no way to tell for sure, but as a general rule, (paraphrase) "Those who thought of and acted on behalf of others in peacetime, did so in combat. Those who thought firstly of themselves in peacetime, also did so in combat."
Best sum up of leadership I've ever read.
Also the responsibilities of commanding a task force, small unit actions, recovering from wounds, getting off a burning ship, running a hospital during a mass cas, calling in artillery danger close, reintegration and 'decompression', homecoming and readjustment, the capture of Stanley, on and on.
GOOD read throughout.
