Why is "GI Underground Press" trending?

Wikipedia Overview

The GI Underground Press was an underground press movement that emerged among the United States military during the Vietnam War. These were newspapers and newsletters produced without official military approval or acceptance; often furtively distributed under the eyes of "the brass". They were overwhelmingly antiwar and most were anti-military, which tended to infuriate the military command and often resulted in swift retaliation and punishment. Mainly written by rank-and-file active duty or recently discharged GIs, AWOLs and deserters, these publications were intended for their peers and spoke the language and aired the complaints of their audience. They became an integral and powerful element of the larger antiwar, radical and revolutionary movements during those years. This is a history largely ignored and even hidden in the retelling of the U.S. military's role in the Vietnam War.
