The continental tactics increasingly emphasized the firepower of the battalion, while the Swedish (Carolean) tactics almost exclusively relied on the shock factor as the infantry and cavalry charged the enemy. As the bayonet was introduced, the pike was discarded in all armies except the Swedish and Russian by 1700. In the Swedish army tactics of that time, retreat was never covered, and they were obliged to attack or fight where they stood. This was a military doctrine that (with the advantage of hindsight) might have proven a bit rash. The infantry shock attack operated as follows. The two rear ranks of musketeers were ordered to shoot when "you could not miss," a range of roughly 50 meters, and then to draw their swords before the battalion resumed their attack. The two foremost ranks then discharged at a range of roughly 20 meters before drawing their swords, and the charge began. At this range, the powerful muskets usually felled many enemy troops and was demoralising to them. Directly after the volley, the Swedes charged the enemy ranks with pikes, bayonets and sabres. Note that the pikes were used as an offensive weapon: in close combat, they had the advantage over their foes' weapons thanks to their range. After the bayonet was introduced in the Carolean army (1700–1706), the final volley was delayed until the soldiers were inside bayonet range. Every infantry battalion had grenadiers attached. They supported the infantry attack by lobbing grenades from the flanks. They also formed units of their own. They were otherwise equipped like infantry. Thus, in the latter half of the 17th century, the major difference between the Swedish army and those common on the continent was the relative lack of firepower and the use of pikes and sabres. Sweden and Russia were the only countries at the time using pikes. In contemporary Europe, infantry were equipped with a musket, while in the Swedish army, every third man had a pike. The pikemen were normally deployed four men deep with musketeers of equal depth on the sides. The pike was used to repulse cavalry and to break the enemy lines as they charged.
