Unconventional Means — Eric Brown

Under cover of illegal immigration and drug smuggling, war has come to America. In a 24- hour period, the upstart El Grupo Cartel simultaneously executes a U.S. Congressman and 52 local, state, and federal officials. The American public wants blood. It's a political nightmare for an administration overwhelmed with a floundering economy, two wars, and waning international influence. They need retribution below the radar, a covert war conducted without the knowledge, sanctioning, or funding from any branch of government; a war that won't make headlines. They need a war using Unconventional Means.
Robert Arminus, a former Special Forces operative betrayed by his own government is picked to lead a team of the military's worst convicts in a 4th generation guerrilla war on U.S. soil. Their objective: disrupt and/or destroy the cartel's billion dollar drug enterprise and execute its leadership that brought war to America.
