Secret Sanction by Brian Haig
It was the worst military scandal since My Lai - an elite US army special forces team positioned behind enemy lines had violated standing orders and butchered a patrol of 25 Serbian soldiers in cold blood. There were no survivors, half of them were shot in the back of the head, and their leader had been decapitated. There was no explanation, and no obvious motive, but the repercussions were already global. Now Major Sean Drummond has to go to Kosovo and find out just what happened and somehow clear up after this horrific crime. But with CIA obstruction, Army hostility, the murder of a top journalist and a possible traitor in his own crew, Drummond quickly finds himself in over his head and under serious fire.
