Query: Sandino, Nicaragua's Nationalist Guerrilla

Outstanding book. Excellent historical account of General Sandino and the genesis of the nationalist struggle in Nicaragua. A little vague on the extent of American commercial interest the US Marines were sent to protect. This book should be read by anyone looking to understand guerrilla warfare. Espcially useful in paralleling combat tactics used by the viet-cong or any nationalist insurgency. Should be required reading for all troopers headed to advise against the FARC and ELN.
