The Eyes of the Hammer by Bob Mayer
From NY Times Best-selling author Bob Mayer:
A US Army Special Forces team carrying sterilized weapons and unmarked uniforms is on its way to Colombia. The mission: conduct covert, unilateral raids to destroy cocaine processing laboratories.
Of course nothing is as it seems especially once the CIA gets involved. Throw in an Israeli mercenary, betrayal and double-dealing in Washington and the team soon finds itself wondering what the real mission is.
