SIG-556

SIG-556 is a character in the mobile game *Girls' Frontline*. She is a Tactical Doll representing the SIG 556 assault rifle. She is described as a teen with shoulder-length gray hair and gray eyes. In the game, SIG-556 is known for her bold and unthinking nature, her fondness for making clothing out of discarded items that she considers stylish, and her smugness about her distinguishing features. She also has a habit of using certain keywords as themes for her clothing styles in the short term. In combat, SIG-556 possesses a skill that dramatically increases her rate of fire and firepower, but this skill can cause overload, requiring manual control to avoid negative status effects. SIG-556's real-world counterpart is the SIG 556 semi-automatic rifle produced by SIGARMS International (now SIG Sauer), a rifle based on the Swiss SG 550 assault rifle, primarily intended for the US civilian and law enforcement market.
