It was one of the most direct options available for attacking a fortification, but was also one of the most dangerous.
 
Fortifications were often constructed in such a way as to impede escalade, or at least to make it a less attractive option. Some of the measures takenCountermeasures to counter escalade included the digging of [[moat]]s (which prevented ladder-bearing soldiers from reaching the base of a wall), the construction of [[machicolation]]s (which facilitated attacks on enemy soldiers while they climbed), and walls incorporating a [[Talus_%28fortification%29Talus (fortification)|talus]] featurewalls (which could weaken ladders or were too tall for ladders to reach the top of).▼

▲Fortifications were often constructed in such a way as to impede escalade, or at least to make it a less attractive option. Some of the measures taken to counter escalade included the digging of [[moat]]s (which prevented ladder-bearing soldiers from reaching the base of a wall), the construction of [[machicolation]]s (which facilitated attacks on enemy soldiers while they climbed), and walls incorporating a [[Talus_%28fortification%29|talus]] feature.
Because of the difficulties involved, escalade was usuallytypically very costly for the attackers. Two critical factors in determining the success or failure of escalade were the number of ladders and the speed with which they could be arranged. A slow attack gave the defenders too much time to pick off the attackers with arrows, while having too few ladders meant that the number of troops would be insufficient to capture the battlements. A third important factor was the estimation of the height of the wall. If the ladders were made too long, they could be pushed over by the defenders, and if they were too short, the attackers would not be able to reach the top of the wall. Tactics employed included getting as many men as possible on the ladder at the same time (the more men that were on the ladder at the same time, the heavier it became, making pushing it over difficult), attacking by night, or scaling a remote section of the wall.▼
 
Escalade was, in essence, an attempt to overwhelm defenders in a [[Frontal assault|direct assault]] rather than sit through a protracted siege. Attackers would generally attempt escalade if they had reasonreasons for wanting a swift conclusion, or if they had an overwhelming superiority in numbers. Otherwise, less costly siege tactics were often preferred.▼

Escalade is no longer common in modern warfare, as new technologies and tactics have essentially made escalade obsolete; for example, most fortified walls that would have required attackers to use escalade may now simply be destroyed by [[Explosive weapon|explosives]] or nullified by [[military aircraft]].
 
However, escalade still exists as a viable (albeit niche) combat tactic, and is occasionally used by [[Police tactical unit|police tactical]], [[Counterterrorism|counterterrorist]], and [[special forces]] units to raid a structure through its upper levels, either to avoid a barricaded entrance or line of sight, or to breach the structure from multiple points. Mechanical assault ladders, typically installed on the roof of vehicles and featuring ramps that can extend or angle themselves to reach an entry point such as a [[window sill]] or [[balcony]], are often used in this capacity.
Modern assaulters sometimes use off-the-shelf ladders or firefighting ladder trucks to attack a building through upper windows and balconies. Purpose-modified vans and trucks with a variety of ramps, ladders, and stairs on the roof are also available. [[SWAT]] teams and other special forces units often put these to use to raid a house through an upper window and the front door simultaneously.
