Tactics
Better-trained troops were capable of using the pike in an aggressive attack with each rank of pikemen being trained to hold their pikes so that they presented enemy infantry with four or five layers of spearheads bristling from the front of the formation.
As long as it kept good order, such a formation could roll right over enemy infantry but it did have weaknesses—as the men were all moving forward they were all facing in a single direction and could not turn quickly or efficiently to protect the vulnerable flanks or rear of the formation and the huge block of men carrying such unwieldy spears could be difficult to maneuver in any way other than straightforward movement.
As a result, such mobile pike formations sought to have supporting troops protect their flanks or would maneuver to smash the enemy before they could be outflanked themselves. There was also the risk that the formation would become disordered, leading to a confused melee in which pikemen had the vulnerabilities mentioned above.
Although primarily a military weapon, the pike could be surprisingly effective in single combat and a number of 16th-century sources explain how it was to be used in a dueling situation; fencers of the time often practiced with and competed against each other with long staves in place of pikes.
