The Pink Guards, otherwise known as Pink Soldiers or Masked Men, are the staff who manage, upkeep, and enforce the rules of the Squid Games on behalf of the Front Man.

Pink Guards all wear the same base clothing in order to preserve anonymity. This is the pink hooded jumpsuit, black gloves and black boots, and a permeated mask to hide their identity. These masks have one of three symbols which indicates their ranking.

Triangle Soldiers are the armed enforcers who terminate eliminated players and prevent contestants from violating the Game's rules. Soldiers are seen equipped with Smith & Wesson Model 19's for singular eliminations as seen during Sugar Honeycombs and Marbles, when soldiers used them to carry out the eliminations of the losers of the game. Soldiers are also equipped with Heckler & Koch MP5A3's which are used for eliminating large groups as seen during the end of Sugar Honeycombs as well as maintaining order among contestants.

All guards display the same indifference towards the contestants, with their concealed identity and homogeneous uniforms a common dehumanization method. Guards are not seen to react to the deaths of contestants through their body language. They also keep standing quietly even if a player talks to them. Although they do not speak, they seem to respond to certain queries from contestants, such as when Player 198's attempt at the Flying Stones stage of the Six-Legged Pentathlon was invalidated, later revealed by the guard that he had stepped over the line as the attempt was made.

Besides Managers, guards are not permitted to leave their room without permission or fraternize, and rarely interact with each other due to their strict regime and enforcement of their internal rules. A sign displayed in Number 29's room translates to:

1. ALWAYS WEAR YOUR MASK OUTSIDE OF YOUR ROOM
2. DO NOT CONVERSE WITHOUT PERMISSION
3. DO NOT LEAVE YOUR ROOM WITHOUT PERMISSION It is therefore unclear whether the guards work for the Squid Games on their own accord or against their will.
