Some recommendations from me...
Afghanistan:
An Ordinary Soldier, by Doug Beattie MC. Just finished this, cracking read from cover to cover.
Descent Into Chaos, by Ahmed Rashid. I found this a good introduction to present-day Afghanistan, causes etc (although I haven't been there so stand by to be corrected!). I also read
Koran Kalashnikov and Laptop by Antonio Giustozzi but didn't find it quite as interesting; it is a hard read.
Bosnia (Srebrenica):
Postcards from the Grave, by Emir Suljagic. Both this and
Endgame by David Rohde deal with the Srebrenica massacre and though admittedly Suljagic is writing from one side of the conflict only, it brings the full scale of the atrocity home.
I'd also like to cast another vote for
Sagittarius Rising by Cecil Lewis - a classic, un-put-down-able! And if you're into fiction and like military satire,
Catch-22 by Joseph Heller is a cracker if you are prepared for a hard read...
