Of the books I've read, "Low Level Hell" (Hugh Mills) I cite as by far and away the best read (even more so than Chickenhawk).
"In The Company Of Heroes" could have been a much better book if the writing standard had been a bit higher, I felt the whole read was a bit dumbed down though. Durants second book, "Night Stalkers" is quite an interesting read (and has a higher writing standard - i attribute that to the presence of a c-writer) though it retells others stories (specifically 160th SOAR pilots) rather than his own.
