Ángel Omar Vivas Perdomo is a Venezuelan Brigadier General.
He has made himself known as an outspoken opponent of the changes introduced to Venezuela armed forces, by going to the supreme court to challenge the introduction of a war cry originally created by Fidel Castro, as the motto for the military in Venezuela.
He was arrested, prosecuted, and on March 1, 2012, sentenced to 4 months and 15 days in jail for having challenged the motto in court.
On 7 April, 2017, he was arrested again during a SEBIN operation that tricked him into helping a young man that hit his car into the front door of his house, three years after a detention order was published during the 2014 Venezuelan protests.
