Revenge of the dog team - William W. Johnstone

William W. Johnstone's Dog Team novels of combat shine a searing light on the Army's most secret lethal force. Now, these heroes are once again called into battle--right on U.S. soil. . .

In the Southwest, a legendary Vietnam-era aircraft disappears--and officials call it a crash in accessible terrain. On the other side of the country, a deadly shipment of nerve gas is loaded onto a secret train--so that no citizen will ever know. . .Now, these two seemingly unconnected events are bringing out the Army's deep "black op" Dog Team. The mysterious operative "Colonel Kilroy" has been working with American Apache trackers to neutralize Iranian agents coming over the Mexican border. While Captain Steve Ireland, the grandson of a Dog Team great, is on a train bound for hell. . .From two sides of the country, one murderous, terrifying plot is closing in like a vice. Once it does, America's only hope will be precision lethal force--aimed hard into the heart of darkness. . .
