Special forces
Army landing operations.

Special Forces Tab: In 1983, nearly 40 years after the end of World War II, the US Army created the Special Forces Tab.  It was later decided that personnel with at least 120 days' wartime service prior to 1955 in certain units, including the Devil's Brigade, the Alamo Scouts and the OSS Operational Groups, would receive the Tab for their services in World War II, placing them all in the lineage of today's U.S. and Canadian (via Devil's Brigade) Special Forces.

Axis powers: The Axis powers did not adopt the use of special forces on the same scale as the British.

German: The German army's Brandenburger Regiment was founded as a special forces unit used by the Abwehr for infiltration and long distance reconnaissance in Fall Weiss of 1939 and the Fall Gelb and Barbarossa campaigns of 1940 and 1941.

Later during the war the 502nd SS Jäger Battalion, commanded by Otto Skorzeny, sowed disorder behind the Allied lines by mis-directing convoys away from the front lines. A handful of his men were captured by the Americans and spread a rumor that Skorzeny was leading a raid on Paris to kill or capture General Dwight Eisenhower. Although this was untrue, Eisenhower was confined to his headquarters for several days and Skorzeny was labelled "the most dangerous man in Europe".

Italian: In Italy, the Decima Flottiglia MAS was responsible for the sinking and damage of considerable British tonnage in the Mediterranean. Also there were other Italian special forces like A.D.R.A. (Arditi Distruttori Regia Aeronautica).  This regiment was used in raids on Allied airbases and railways in North Africa in 1943. In one mission they destroyed 25 B-17 Flying Fortress bombers.

Japanese: The Imperial Japanese Army first deployed army paratroops in combat during the Battle of Palembang, on Sumatra in the Netherlands East Indies, on 14 February 1942. The operation was well-planned, with 425 men of the 1st Parachute Raiding Regiment seizing Palembang airfield, while the paratroopers of the 2nd Parachute Raiding Regiment seized the town and its important oil refinery. Paratroops were subsequently deployed in the Burma campaign. The 1st Glider Tank Troop was formed in 1943, with four Type 95 Ha-Go light tanks. The paratroop brigades were organized into the Teishin Shudan as the first division-level raiding unit, at the main Japanese airborne base, Karasehara Airfield, Kyūshū, Japan.
However, as with similar airborne units created by the Allies and other Axis powers, the Japanese paratroops suffered from a disproportionately high casualty rate, and the loss of men who required such extensive and expensive training limited their operations to only the most critical ones. Two regiments of Teishin Shudan were formed into the 1st Raiding Group, commanded by Major General Rikichi Tsukada under the control of the Southern Expeditionary Army Group, during the Philippines campaign. Although structured as a division, its capabilities were much lower, as its six regiments had manpower equivalent to a standard infantry battalion, and it lacked any form of artillery, and had to rely on other units for logistical support. Its men were no longer parachute-trained, but relied on aircraft for transport.
Some 750 men from the 2nd Raiding Brigade, of this group were assigned to attack American air bases on Luzon and Leyte on the night of 6 December 1944. They were flown in Ki-57 transports, but most of the aircraft were shot down. Some 300 commandos managed to land in the Burauen area on Leyte. The force destroyed some planes and inflicted numerous casualties, before they were annihilated.

Finnish: During World War II, the Finnish Army and Border Guard organized sissi forces into a long-range reconnaissance patrol (kaukopartio) units. These were open only to volunteers and operated far behind enemy lines in small teams. They conducted both intelligence-gathering missions and raids on e.g. enemy supply depots or other strategic targets. They were generally highly effective. For example, during the Battle of Ilomantsi, Soviet supply lines were harassed to the point that the Soviet artillery was unable to exploit its massive numerical advantage over Finnish artillery. Their operations were also classified as secret because of the political sensitivity of such operations. Only authorized military historians could publish on their operations; individual soldiers were required to take the secrets to the grave. A famous LRRP commander was Lauri Törni, who later joined the U.S. Army to train U.S. personnel in special operations.

Bangladesh Liberation War (1971): In June 1971, during the Bangladesh Liberation War, the World Bank sent a mission to observe the situation in East Pakistan. The media cell of Pakistan's government was circulating the news that the situation in East Pakistan was stable and normal. Khaled Mosharraf, a sector commander of Mukti Bahini, planned to deploy a special commando team. The task assigned to the team was to carry out commando operations and to terrorize Dhaka. The major objective of this team was to prove that the situation was not actually normal. Moreover, Pakistan, at that time, was expecting economic aid from World Bank, which was assumed to be spent to buy arms. The plan was to make World Bank Mission understand the true situation of East Pakistan and to stop sanctioning the aid. Khaled, along with A. T. M. Haider, another sector commander, formed the Crack Platoon. Initially, the number of commandos in the platoon was 17, trained in Melaghar Camp. From Melaghar, commandos of Crack Platoon headed for Dhaka on 4 June 1971 and launched a guerrilla operation on 5 June. Later, the number of commandos increased, the platoon split and deployed in different areas surrounding Dhaka city. The basic objectives of the Crack Platoon were to demonstrate the strength of Mukti Bahini, terrorising Pakistan Army and their collaborators. Another major objective was proving to the international community that the situation in East Pakistan was not normal. That commando team also aimed at inspiring the people of Dhaka, who were frequently victims of killing and torture. The Crack Platoon successfully fulfilled these objectives. The World Bank mission, in its report, clearly described the hazardous situation prevailing in East Pakistan and urged ending the military regime in East Pakistan. The Crack Platoon carried out several successful and important operations. The power supply in Dhaka was devastated which caused severe problems for the Pakistan Army and the military administration in Dhaka.

Modern special forces: Admiral William H. McRaven, formerly the ninth commanding officer of the U.S. Special Operations Command (2011–2014), described two approaches to special forces operations in the 2012 posture statement to the U.S. Senate Committee on Armed Services: "the direct approach is characterized by technologically enabled small-unit precision lethality,  focused intelligence,  and inter-agency cooperation integrated on a digitally-networked battlefield", whereas the "indirect approach includes empowering host nation forces, providing appropriate assistance to humanitarian agencies, and engaging key populations."  Elements of national power must be deployed in concert without over-reliance on a single capability, such as special forces, that leaves the entire force unprepared and hollow across the spectrum of military operations.

Throughout the latter half of the 20th century and into the 21st century, special forces have come to higher prominence, as governments have found objectives can sometimes be better achieved by a small team of anonymous specialists than a larger and much more politically controversial conventional deployment. In both Kosovo and Afghanistan, special forces were used to co-ordinate activities between local guerrilla fighters and air power. Typically, guerrilla fighters would engage enemy soldiers and tanks causing them to move, where they could be seen and attacked from the air.

Special forces have been used in both wartime and peacetime military operations such as the Laotian Civil War, Bangladesh Liberation War-1971, Vietnam War, Portuguese Colonial War, South African Border War, Falklands War, The Troubles in Northern Ireland, the Jaffna University Helidrop, the first and second Gulf Wars, Afghanistan, Croatia, Kosovo, Bosnia, the first and second Chechen Wars, the Iranian Embassy siege (London), the Air France Flight 8969 (Marseille), Operation Defensive Shield, Operation Khukri, the Moscow theater hostage crisis, Operation Orchard, the Japanese Embassy hostage crisis (Lima), in Sri Lanka against the LTTE, the raid on Osama Bin Laden's compound in Pakistan, the 2016 Indian Line of Control strike the 2015 Indian counter-insurgency operation in Myanmar and the Barisha Raid in Syria of 2019.
The U.S. invasion of Afghanistan involved special forces from several coalition nations, who played a major role in removing the Taliban from power in 2001–2002. Special forces have continued to play a role in combating the Taliban in subsequent operations.
As gender restrictions are being removed in parts of the world, females are applying for special forces units selections and in 2014 the Norwegian Special Operation Forces established an all female unit Jegertroppen (English: Hunter Troop).

Tier One units: These are the highest level of military special forces, as in the highest trained and usually the most secretive.
