Bolo: The Annals of the Dinochrome Brigade
Collection of short stories, following increasing marks of the self aware tanks known as Bolos.There are several other short story collections (that came out in the 90's?) with different authors, but this is the best one, being typically 70's sci-fi.
Laumer does a great job of showing the "humanity" of these machines, as well as the people who work with them.
(And the reaction when someone sees a giant super tank for the first time).
