線列步兵最早出現在17世紀後期。在17世紀初，瑞典國王古斯塔夫二世決定以簧輪式火器武裝他的陸軍，但只有騎兵裝備了這種結構複雜的武器。他在三十年戰爭期間的使用的戰術被認爲是線式戰術的先行，但其發展仍能等到世界末才成形。在他逝世後的壹段時間，瑞典步兵便以新式簧輪式火槍武裝，與舊式火槍相比，新式火槍比較輕，更加容易發射，不需要額外幫助。另外，制作新式火槍，需要的鐵更少，意味著在大量生産時，更加便宜。這種火器的出現，使得需要大量裝備火槍的線列步兵的創立變得可能。
Line infantry first appeared in the late 17th century. In the early 17th century, King Gustav II of Sweden decided to arm his army with spring-loaded firearms, but only the cavalry was equipped with this complex weapon. His tactics during the Thirty Years' War are considered to be the forerunners of line tactics, but its development still took shape until the end of the world. Some time after his death, Swedish infantry were armed with new spring-loaded muskets, which were lighter and easier to fire than the old ones, and did not require additional aids. In addition, the new muskets required less iron to make, which meant that they were cheaper when mass-produced. The emergence of this firearm made it possible to create line infantry, which required large numbers of muskets.
