The US were against the government of Salvador Allende in Chile because he was a Marxist and they feared this would increase the influence of communism in the Western hemisphere.
Explanation:
The United States intervened in the presidency of Salvador Allende and supported a military coup by Augusto Pinochet, that would lead to the death of Salvador Allende and the instillation of a military dictatorship in Chile that lasted from 1974-1990. The actions that would actively undermine the Allende government were supported by the US government and the CIA because Allende had Marxist views that when against the liberal democracy ideals of the United States government. Intervention helped assure that there would not be a further spread of communism in Latin America that could threaten the sphere of influence of the United States. I think that the United States shouldn't intervene in the sovereign systems of other countries and that the US should have faced charges of human rights violations for the death of General René Schneider who the CIA paid $50,000 to have kidnapped and delivered weapons to the pro-coup factions who were after Schneider.
Soldiers were drilled in infantry tactics, usually based upon a manual written before the war by West Point professor William J. Hardee (Rifle and Light Infantry Tactics: for the Instruction, Exercise and Maneuver of Riflemen and Light Infantry, published in 1855).
