Stalcraft Wiki: Hoplite Armored Suit

In-game description (EXBO)

The main distinguishing feature of Hoplite compared to the cheaper Red Shield suits is the reinforced gas mask, which proves to be extremely useful in the Zone. Despite providing decent protection, the armored suit was not designed for the Zone, which affects its anomalous effects protection.
