The meaning of the phrase is context sensitive, and has varied over time, like the difference between "strategy" and "tactics".[1]
General
Exploiting prevailing weather – the tactical use of weather as a force multiplier has influenced many important battles throughout history, such as the Battle of Waterloo.[2]
Fire attacks – reconnaissance by fire is used by apprehensive soldiers when they suspect the enemy is nearby.
Force concentration – the practice of concentrating a military force against a portion of an enemy force.[3]
Night combat – combat that takes place at night. It often requires more preparation than combat during daylight and can provide significant tactical advantages and disadvantages to both the attacker and defender.[4]
Reconnaissance – a mission to obtain information by visual observation or other detection methods, about the activities and resources of the enemy or potential enemy, or about the meteorologic, hydrographic, or geographic characteristics of a particular area.[5]
Smoke screening – the practice of creating clouds of smoke positioned to provide concealment, allowing military forces to advance or retreat across open terrain without coming under direct fire from the enemy.[6]
Penetration of the center: This involves exploiting a gap in the enemy line to drive directly to the enemy's command or base. Two ways of accomplishing this are separating enemy forces then using a reserve to exploit the gap (e.g., Battle of Chaeronea (338 BC)) or having fast, elite forces smash at a weak spot (or an area where your elites are at their best in striking power) and using reserves to hold the line while the elite forces continue forward, exploiting the gap immediately (i.e., blitzkrieg).
Attack from a defensive position: Establishing a strong defensive position from which to defend and attack your opponent (e.g., Siege of Alesia and the Battle of the Granicus). However, the defensive can become too passive and result in ultimate defeat.
Single envelopment: A consolidated prong (flank) beating its opponent opposite end, and with the aid of holding attacks, attack an opponent in the rear. Sometimes, the establishment of a strong, hidden force behind a weak flank will prevent your opponent from carrying out their own single envelopment. (e.g., Battle of Rocroi).
Double envelopment: Both flanks defeat their opponent opposite and launch a rear attack on the enemy center. Its most famous use was Hannibal's tactical masterpiece, the Battle of Cannae, and it was frequently used by the Wehrmacht on the Eastern Front of World War II. It was also executed to perfection by Khalid ibn al-Walid in the decisive Battle of Yarmuk in 636 AD.
Attack in oblique order: This involves placing your flanks in a slanted fashion (refusing one's flank) or giving a vast part of your force to a single flank (e.g., Battle of Leuthen). The latter can be disastrous, however, due to the imbalance of force.
Feigned retreat: Having a frontal force fake a retreat, drawing the opponent in pursuit and then launching an assault with strong force held in reserve (such as the Battle of Maling and the Battle of Hastings). However, a feigned retreat may devolve into a real one, such as in the Battle of Grunwald.
Indirect approach: Having a minority of your force demonstrate in front of your opponent while the majority of your force advance from a hidden area and attack the enemy in the rear or flank (e.g., Battle of Chancellorsville).
Crossing the "T": a classic naval maneuver which maximizes one side's offensive firepower while minimizing that of the opposing force (e.g., Battle of Trafalgar).
Tactics
Deception
In the 4th century BCE, Sun Tzu said "the Military is a Tao of deception".[7] Diversionary attacks, feints, decoys; there are thousands of tricks that have been successfully used in warfare, and still have a role in the modern day.
Perfidy: Combatants tend to have assumptions and ideas of rules and fair practices in combat. Those who raise surrender flags to lure their attackers in the open, or who act as stretcher bearers to deceive their targets, tend to get especially disliked.
False flag: An ancient ruse de guerre – in the days of sail, it was permissible for a warship to fly the flag of an enemy power, so long as it properly hoisted its true colors before attacking. Wearing enemy uniforms and using enemy equipment to infiltrate or achieve surprise is also permissible though they can be punished as spies if caught behind enemy lines.
Demoralization (warfare): A process in psychological warfare that can encourage them to retreat, surrender, or defect by deterioration of the opposite force's morale rather than defeating them in a regular warfare.
Blitzkrieg – a method of warfare whereby an attacking force is spearheaded by a dense concentration of armoured and motorized or mechanized infantry formations, and heavily backed up by close air support.[8]
Carpet bombing – also known as saturation bombing, is a large aerial bombing done in a progressive manner to inflict damage in every part of a selected area of land.[9]
Pincer movement – an army assaults an enemy by attacking two sides at opposite locations, often planning to cut off the enemy from retreat or additional support in preparation for annihilation.
Bull horn formation – an army assaults an enemy force by sending troops to the enemy's flanks and by attacking their front attacking three areas at once, often planning to cut off any retreat or support as well as confusing the enemy in preparation for annihilation.
Raiding – a small team is inserted deep behind enemy lines to capture a high-value individual or destroy a vital enemy installation then extracted before the enemy can respond.
Exhausting - sending in small teams of soldiers to wear out the enemy each day and then strike with all of your forces.
Fire and movement (also known as leapfrogging) – working in 'fire teams', one team attempts to suppress the enemy while the other moves either toward the enemy or to a more favourable position.
Basic drill – a standard drill that all individual soldiers are supposed to perform if they come under fire.
Sniper trap – A sniper trap (colloquial term in US military “Chechen rat trap”) is a tactic used by snipers in which the sniper intentionally shoots to wound instead of kill an enemy combatant, with the end goal of drawing more enemy personnel into the field of fire so the sniper can fire on them as they provide aid to their wounded comrade. Not only does this tactic provide more targets for the sniper as enemy personnel come to help the wounded, but it also causes the sniper’s enemy to expend more resources in recovering, evacuating, and treating the wounded combatant than would be expended if the sniper simply killed the enemy combatant.
