The embattled second-term leader cut ties with the US Wednesday after the Trump administration recognized opposition leader Juan Guiado as Venezuela's interim president, a move Maduro blasted as an attempted coup.
At a Caracas rally the Guaido said he would announce a date for "a grand march", and called on supporters to circulate copies of amnesty measures approved by the National Assembly to friends and relatives in the military.
Encouraged by the global support for his cause, Guaido is on a mission to weaken the military's support of Maduro, which has been essential to keeping him in power since 2013.
In a video posted online on Saturday Silva urged "my brothers in the national armed forces" to recognize Guaido "as the only legitimate president", in accordance with Venezuela's constitution.

They should take back this ultimatum. In an interview on Sunday with CNN Turk, Maduro claimed that he was the "the victim of a U.S. conspiracy" that had resulted in the threat to his power.
Israel reportedly demurred, fearing that enraging Maduro could endanger members of the 6,000-strong Venezuelan Jewish community. Everybody can see the security guards who protect Maduro.
