The video showcases hidden trap doors, revolving spikes and other improvised weaponry that proved a crucial component of the Viet Cong's guerrilla tactics against the superior firepower of the U.S. military.

Accustomed to their homeland's dense jungle surroundings, the idea was to create hidden traps in the undergrowth that effectively hindered GIs' ability to pursue the Viet Cong's retreating forces.

According to History Hit many of the traps were "designed to maim instead of kill" and had a two-pronged effect.

"Not only did this mean other soldiers were required to remove their wounded colleagues which hampered operations, but it also meant the traps were a psychological weapon as word about them spread," they explained.

It's estimated that as many as 11 percent of deaths and 15 percent of wounds to U.S. soldiers during the conflict were a result of the kind of booby traps and landmines showcased in the clip.

The clip drew shocked reactions on Reddit with Mandascuck branding the traps "resourcefully brutal" and LoneWolf_855 agreeing they were "horrifying."

For users like Salt-Birthday-5527 imagining what the American GIs' fighting in the conflict must have gone through was almost too much to bear.

"The boys went in thinking they were saviors to the local people," they wrote. "This is dark age brutality. The boys went through hell."

One user, posting as Leelee1976, claimed his father fought in Vietnam and told him "they refused to find out the new recruits name until they had been in the unit for more than 90 days" on account of the number of new recruits who would be killed within that time.

Another, posting as Vegetablelasagnaaaa added that many of the spikes used in these traps "were covered in excrement" in order to "heed infection."

According to U.S. Wings, young recruits did indeed make up the majority of U.S. casualties with some 61% younger than 21 years old when they died. The average age of the men killed during the conflict was also 23.1 years.

History Collection also confirms the claims that spikes were often contaminated to encourage infection.

They say the Viet Cong "made punji stakes out of heated and sharpened wood or bamboo" and would often "smear the tip of the stakes with urine, feces, poison, or other contaminants to infect the wound when it penetrated the skin."
