The Tankmen are soldiers with a monochromatic color scheme; all of their helmets, uniforms, gloves, pants and boots are black, while their skin, goggles and vests are white. Most Tankmen are seen with helmets with the standard rectangular goggles, though an exceptional few have round goggles instead.
During the tracks Ugh and Guns, there are 2 Tankmen in the foreground seen resting their feet on the 2 smaller speakers that lay beside the large speaker Girlfriend sits on. They both have insignias on their arm and carry rifles which they point at Girlfriend. The soldier on the left has round goggles while the soldier on the right has rectangular ones.
During the track Stress, the 2 Tankmen on either side of Girlfriend are now gone, both having been killed by Pico during the track's cutscene. Many other Tankmen soldiers with insignias on their arms, carrying rifles will now run in from the background, each one being shot and killed by Pico once they appear.
Throughout all tracks of the week, there is an audience of 6 visible Tankmen. Steve, a Tankmen soldier with round goggles and Tankman's best friend, can occasionally be seen in the background, driving by in a tank.
- The Tankmen are the second characters to be on the speakers in some way, the first being Girlfriend and the third being Pico.
- The Tankmen are also the third characters to die, the first being Santa Claus and the second being Senpai.
- In the TANKMEN series, Steve is the only soldier known to wear round goggles, which helped to distinguish him from the other Tankmen soldiers in the series. In-game, there are two Tankmen soldiers seen with round goggles. However, Steve is likely to be the one driving the tank in the background as he has been shown to be able to operate it before in his series. Additionally, the left Tankman in the foreground has insignias on his arm, something that Steve never had in the series.
- PhantomArcade directly refers to the one driving the tank as Steve during a livestream.
- As seen originally on the livestream where PhantomArcade briefly and accidentally leaked Tankman, both Tankmen soldiers in the foreground used to look identical to each other. However, the soldier to the left would later be changed by being given round goggles.
- The Tankmen are confirmed to be asexual by JohhnyUtah in a tweet.
