Psychology
A tracker needs to pay close attention to both the environment and the psychology of his enemy. Knowledge of human psychology, sociology, and cultural backgrounds is necessary to know the actions of the enemy and where the enemy is heading. The celebrated Chief of Scouts
Frederick Russell Burnham

had this to say:
It is imperative that a scout should know the history, tradition, religion, social customs, and superstitions of whatever country or people he is called on to work in or among. This is almost as necessary as to know the physical character of the country, its climate and products. Certain people will do certain things almost without fail. Certain other things, perfectly feasible, they will not do. There is no danger of knowing too much of the mental habits of an enemy. One should neither underestimate the enemy nor credit him with superhuman powers. Fear and courage are latent in every human being, though roused into activity by very diverse means.

While typical reconnaissance forces are small and armed only for self-defense, RIF use considerable (but not decisive) force in order to elicit a strong reaction by the enemy that more accurately reveals its own strength, deployment, preparedness, determination, and other tactical data. The RIF units can then fall back and report this data, or expand the conflict into a full engagement if enemy weaknesses are revealed.

Maintaining active RIF can be used to limit, or even deny, enemy reconnaissance.
Nazi Germany's reconnaissance during World War II is described in the following way:
The purpose of reconnaissance and the types of units employed to obtain information are similar in the U.S. and the German Armies. German tactical principles of reconnaissance, however, diverge somewhat from those of the U.S. The Germans stress aggressiveness, attempt to obtain superiority in the area to be reconnoitered, and strive for continuous observation of the enemy. They believe in employing reconnaissance units in force as a rule. They expect and are prepared to fight to obtain the desired information. Often they assign supplementary tasks to their reconnaissance units, such as sabotage behind enemy lines, harassment, or counter-reconnaissance.
Only enough reconnaissance troops are sent on a mission to assure superiority in the area to be reconnoitred. Reserves are kept on hand to be committed when the reconnaissance must be intensified, when the original force meets strong enemy opposition, or when the direction and area to be reconnoitred are changed. The Germans encourage aggressive action against enemy security forces. When their reconnaissance units meet superior enemy forces, they fight a delaying action while other units attempt to flank the enemy.

s determined that the Japanese defenders had largely ignored the northern beaches of the island, focusing most of their defensive effort on beaches in the south-west which were more favorable for an amphibious landing. American forces quickly changed their landing location to the northern beaches and planned a small and hasty "deception" operation off the southern beach, which resulted in a complete surprise for the Japanese forces. As a result, American forces were able to fight the Japanese force on land, where they had the advantage, leading to light losses and a
relatively short battle that lasted only 9 days.

Area
![Montagnards in field](https://upload.wikimedia.org/wikipedia/commons/2/28/Montagnards_in_field.png)
Area reconnaissance refers to the observation, and information obtained, about a specified location and the area around it; it may be terrain-oriented and/or force-oriented. Ideally, a reconnaissance platoon, or team, would use surveillance or vantage (static) points around the objective to observe, and the surrounding area. This methodology focuses mainly prior to moving forces into or near a specified area; the military commander may utilize his reconnaissance assets to conduct an area reconnaissance to avoid being surprised by unsuitable terrain conditions, or most importantly, unexpected enemy forces. The area could be a town, ridge-line, woods, or another feature that friendly forces intend to occupy, pass through, or avoid.
Within an
area of operation (AO), area reconnaissance can focus the reconnaissance on the specific area that is critical to the commander. This technique of focusing the reconnaissance also permits the mission to be accomplished more quickly. Area reconnaissance can thus be a stand-alone mission or a task to a section or the platoon. The commander analyzes the mission to determine whether the platoon will conduct these types of reconnaissance separately or in conjunction with each other.
Civil
Civil reconnaissance is the process of gathering a broad spectrum of civil information about a specific population in support of military operations. It is related to and often performed in conjunction with infrastructure reconnaissance (assessment and survey). Normally the focus of collection in the operational area for civil reconnaissance is collecting civil information relating to the daily interaction between civilians and military forces. Civil information encompasses relational, temporal, geospatial and behavioral information captured in a socio-cultural backdrop. It is information developed from data related to civil areas, structures, capabilities, organizations, people, and events, within the civil component of the commander's operational environment that can be processed to increase situational awareness and understanding. The type of civil information that is needed in order to support military operations varies based on the environment and situation.

s or pickup zones, if the need arises.
In many cases, the commander may act upon a ''force-oriented'' route reconnaissance by which the enemy could influence movement along that route. For the reconnaissance platoons, or squads, stealth and speed—in conjunction with detailed intelligence-reporting—are most important and crucial. The reconnaissance platoon must remain far enough ahead of the maneuver force to assist in early warning and to prevent the force from becoming surprised.
Even it is paramount to obtain information about the available space in which a force can maneuver without being forced to bunch up due to obstacles. ''Terrain-oriented'' route reconnaissance allows the commander to obtain information and capabilities about the adjacent terrain for maneuvering his forces, to include, any obstacles (minefields, barriers, steep ravines, marshy areas, or

contamination) that may obstruct vehicle movement—on routes to, and in, his assigned area of operations. This requirement includes the size of trees and the density of forests due to their effects on vehicle movement. Route reconnaissance also allows the observation for fields of fire along the route and adjacent terrain. This information assists planners as a supplement to map information.
Zone
Zone reconnaissance focuses on obtaining detailed information before maneuvering their forces through particular, designated locations. It can be terrain-oriented, force-oriented, or both, as it acquire this information by reconnoitering within—and by maintaining surveillance over—routes, obstacles (to include nuclear-radiological, biological, and chemical contamination), and resources within an assigned location.
Also, ''force-oriented'' zone reconnaissance is assigned to gain detailed information about enemy forces within the zone, or when the enemy situation is vague by which the information concerning cross-country traffic-ability is desired.
The reconnaissance provides the commander with a detailed picture of how the enemy has occupied the zone, enabling him to choose the appropriate course-of-action.
As the platoon conducts this type of zone reconnaissance, its emphasis is on determining the enemy's locations, strengths, and weaknesses. This is the most thorough and complete reconnaissance mission and therefore is very time-intensive.
