Last week a group of men in Venezuelan army uniforms released a video from Peru saying that they were rebelling against the Maduro regime. They cited the constitution, and said that they did not recognize Maduro as president or commander in chief, and that they recognized National Assembly president Juan Guaido as interim president of Venezuela.
Here's the video:

The video was strange because it was recorded in Peru. I think that the people in the video are deserters who simply kept their uniforms when they left Venezuela and ended up in Peru.
I didn't really think much of the video until yesterday, when a second similar video was shared online, this one recorded in Colombia. In this second video, the men in uniform also say that they support Guaido, and that they are teaming up with the Peruvian group and "heading to the border", presumably to launch some kind of guerrilla war against the regime.
This is the video:

I saw a lot of talk on Twitter about what the videos might mean, and if they might be a sign of an escalation. I think that more than anything else, these kinds of videos are meant to persuade army units inside Venezuela to rebel. It's impossible to tell how big this group of rebels might be, but it's probably 20-40 strong. I don't know exactly what these people are hoping to accomplish by heading to the border (and then...? Fighting the Venezuelan army? Liberating towns?), so until we see some concrete action I can't say that I think these videos amount to much.
