The SG553 is a slightly improved version of the SG552, the compact version of the SIG SG550, the standard rifle of the Swiss Army. It fires the 5.56x45mm NATO round from a 5, 10, 20 or 30 round magazine at 700 RPM. The SG553 was made for more urban environments, where its shorter length makes it a formidable close range tool. Even with its short barrel, the rifle is highly accurate out to ~200–250 meters.
The SG553 appears in three games in the Battlefield series.
