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.
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.
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.
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.
Battle of Maling, the earliest known use of the feigned retreat
Single envelopment: A strong flank beating its opponent opposite 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 was frequently used by the Wehrmacht on the Eastern Front of World War II. It was also executed to prefection 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.
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).
In the 4th century BCE, Sun Tzu said "the Military is a Tao of deception". 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, but the ones who raise surrender flags to lure their attackers in the open, or who act as stretcher bearers to deceive their targets, tend to be 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 rather than defeating them in combat.
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.
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.

A holding attack is an attack designed to fix the enemy in position, to prevent him from reinforcing the elements opposing the main attack, and/or to cause him to commit his reserves prematurely at an indecisive location. A holding attack is the most common type of supporting attack. Typically, it is launched frontally against an enemy position while the main attack outflanks or envelops the enemy.
