The senior Romney asked "special favors" for his son and for himself. They wanted to be "special rangers" was the term the elder Romney used. The military first checked with Washington and was ordered to assist the Romneys.
Here's how one who served in Viet Nam described to a Senate subcommittee what the Romneys did to Vietnamese villagers.
Both father and son have
"raped, cut off ears, cut off heads, taped wires from portable telephones to human genitals and turned up the power, cut off limbs, blown up bodies, randomly shot at civilians, razed villages in fashion reminiscent of Ghengis Khan, shot cattle and dogs for fun, poisoned food stocks, and generally ravaged the countryside of South Vietnam . . . ."
My emphasis. They first tied the dogs to the tops of military vehicles, others said.
