Remember, VERY IMPORTANT, that marxist Allende had his own communist militia in Chile and it was attacking the middle class and working class protestors.
That is one reason the military stepped in and took over. They knew that the communist militias were receiving weapons and training, esp. from the Cuban DGI and military advisors Allende had let into the country.
See the “White Book on Chile” for photos and details about this. It was published after Allende was ousted and offed himself. The military found all kinds of arms caches throughout the capital and some in the countryside.
In Venezuela the top brass also hold government positions and the military is well “taken care of” by the regime. More admirals than ships, if you know what I mean. They own factories and all kinds of stuff.
