Combat uniform

A combat uniform, also called a field uniform, battledress, or military fatigues, is a casual uniform used by military, police, fire, and other public uniformed services for everyday fieldwork and duty, as opposed to dress uniforms for formal functions and parades. It generally consists of a jacket, trousers, and shirt or T-shirt, all cut to be looser and more comfortable than more formal uniforms. Combat uniform designs vary by regiment or service branch. Uniform fabrics often come in camouflage, disruptive patterns, or otherwise olive drab, brown, or khaki monochrome, to approximate the background and make the soldier less conspicuous in the field. In Western dress codes, field uniforms are considered equivalent to civilian casual wear, less formal than service dress uniforms, which are generally for office or staff use, as well as mess dress uniforms and full dress uniforms.
Combat uniforms have existed to some degree in most organized militaries throughout history, with the intent of providing both protection and easy identification. The British Indian Army's Corps of Guides were the first to use drab combat uniforms starting in 1848, when they wore light-brown clothing called "khaki" by Indian troops. The Second Boer War and World War I ended the pre-modern practice of issuing brightly-colored combat uniforms in favor of green, brown, khaki, and grey uniforms that better suited the varied environments of modern warfare. The first proper military camouflage pattern was Italy's telo mimetico, originally designed for half-shelters in 1929. Germany's Wehrmacht began issuing camouflage uniforms to paratroopers during World War II, and by the end of the war, both the Allies and Axis made use of camouflage uniforms for select units, usually special forces. The Cold War and post–Cold War era saw the gradual shift from monochromatic olive and khaki combat uniforms to those using camouflage patterns.

Terminology

In British English, battledress is often the preferred name. In American English, the term fatigues has often been used by the Army, or utilities by the Marines, originally being a term for work uniforms. In the late- and post-Cold War era, the term battle dress uniform is used most often to describe combat uniforms in general.

Combat uniforms by country

Australia

generally followed British-style uniforms, but did not join other Commonwealth countries in adopting the British Battledress during World War II; instead, Australia continued to use a slightly updated version of the uniform worn during World War I, which continued into the Korean War. Following service with the 28th Commonwealth Division in Malaya and Borneo, Australia adopted "Jungle Greens" for all field wear, eventually modifying the uniform during the Vietnam War with slanted pockets and with the blouse to be worn outside of the trousers, similar to U.S. "jungle fatigues" which also first appeared in Vietnam. The modified JGs were colloquially called the "Pixie suit." JGs were worn through the 1970s and until the adoption of Australia's own camouflage pattern called Disruptive Pattern Combat Uniform introduced from 1982. There were also multiple patterns based on DPCU, including the Disruptive Pattern Desert Uniform, and a red/white version for OPFOR teams during combat exercises
The Australian Defence Force has, as of 2014, introduced the Australian Multicam Camouflage Uniform for Army and Air Force personnel engaged in warlike activities, and for Air Force field exercises. There is two main variants of AMCU available to AA and RAAF troops, the Field Uniform, the standard uniform cut seen since LAND125 Phase 4. It features 2 breast pockets, an epaulette on the chest, a pocket on either upper sleeve, two front trouser pockets, 2 side zip pockets and a pocket to slip in kneepads. The AMCU Field variant is worn by the army as barracks dress. The second variation is the AMCU Combat Uniform. It features a knitted section around the torso for breathability under body armour, and 2 slanted sleeve pockets along with reduced amounts of pockets on the trousers to increase dexterity and breathability.

Canada

The first true battledress adopted by Canada for standard issue across the board was the khaki field uniform known as Service Dress, adopted in 1907. This was of a separate pattern from the British Service Dress adopted after the Boer War, and marked a departure in Canadian uniforms in that it was distinct from the scarlet/blue/rifle green uniforms traditionally worn to that point, the latter of which became "ceremonial" dress for parades and other functions apart from field training.
Until well into the Cold War era, the Canadian Army had worn battle dress uniforms similar to their British and Commonwealth counterparts, though with different national identifiers and regimental accoutrements. In the early 1950s, battle dress began to be replaced with lightweight uniforms, at first Bush Dress for summer wear, and in the 1960s with a new combat dress, a set of olive drab garments more similar to the American style of combat wear.

Service Dress (1907–1940)

Canadian pattern Service Dress worn by other ranks did not stand up to the rigors of campaigning, however, and was widely replaced by British uniforms in France; some samples of Canadian pattern SD were retained in Canada, and after the war, surviving to be issued briefly in 1939.
Officers wore a distinctive pattern of Service Dress, which was identical to that worn by British officers; they were privately purchased, and of better quality than other ranks uniform. In combat in France and Flanders, they were often replaced on an individual basis by other ranks' Service Dress, making the officer less conspicuous to enemy snipers and soldiers.

Khaki Drill (1900–1949)

was a series of different uniform patterns of light khaki cloth, generally cotton, first worn by Canadian soldiers in the Boer War and reserved for summer training in Canada, or for employment in tropical climates. Canada developed its own pattern after the First World War, and the uniform was commonly worn in Canada, with officers again having the option of finer garments privately purchased. In the Second World War, Canadians serving in Jamaica and Hong Kong wore Canadian pattern KD; the I Canadian Corps troops in Italy wore KD supplied in theatre by the British, generally of British, Indian or US manufacture.
Worn in tropics far beyond 1949. KD was still in issue and worn with either short or long trousers as parade dress. Jacket was replaced with shirt for normal barrack dress wear. Worn by all British units in Kenya until Dec 1964. Also in issue and worn by British Honduras Garrison and attached Infantry Company Group until at least 1968.

Battle Dress (1939–1970)

In 1939, the Battle Dress uniform was adopted as a field uniform; made of wool and patterned after British BD, Canadian uniforms were darker in color with a distinctive green tinge to the dark khaki color. Officers had the option of having BD tailored from better material, but in the field most wore "off the rack" BD, perhaps with a modified open collar.
Battle Dress was worn in 1939 and into 1940 by soldiers in Canada as field dress, and afterward was no longer issued except to a select few. While a new pattern of Service Dress was introduced for Other Ranks in this period, it was reserved for dress wear only. Battle Dress completely replaced SD as a field uniform beginning in 1940 as enough of the new uniforms became available.
A new pattern of BD was introduced in 1949, with an open collar matching that of British Pattern 1949 BD. The garment was worn as a field dress throughout the Korean War, and into the 1960s until replaced by the Combat uniform. Some Militia units used BD as a dress uniform until the early 1970s.
The US Army produced its own version of the BD blouse for issue to soldiers in Europe. Although most of these were produced in England, they were of a dark green color, rather than khaki. Called the ETO jacket, American soldiers dubbed it the Ike Jacket, after General Dwight D. Eisenhower.

Bush Dress (1950–1960)

Bush Dress was a series of dark green cotton uniforms, similar to KD clothing, which replaced those uniforms just prior to the Korean War. Like KD, Bush Dress was worn primarily as a field uniform. It was replaced by the Combat uniform in the 1960s.

Combats (1960–2000)

The green combat uniform became universal battledress in the 1960s, and was designed to be worn in any environment.
The Canadian pattern combat uniform had angled pockets, designed to take magazines from the FN C1A1 battle rifle; a truly poor design of infantry load bearing equipment inspired this design – the 1964 Pattern Web Equipment had no ammunition pouches. The angled pockets are repeated on the new CADPAT uniform, though they are enlarged and not intended for ammunition carriage.
The Canadian combat uniform had a high nylon content, which had the potential for producing significant burns.

CADPAT (2000–present)

In Canada, battledress is referred to officially as "No. 5 Operational Dress", and in general parlance as "combat uniform" or "combats". The new Canadian Disruptive Pattern uniform is commonly called "CADPAT" to diffentiate it from the previous uniform called "combat". The term combat now refers to the old monochrome combat uniform.
Currently, the Canadian Forces use the four-colour CADPAT design, a computer-generated pixelated pattern issued in TW and AR colours. Camouflage cloth of CADPAT pattern was created and adopted in 1995, used for issue helmet covers in 1997 and trousers and blouses in CADPAT began to replace the olive green combat uniform from 2001 when Canadian forces joined the UN peacekeepers in Bosnia-Hercegovina. The AR version was introduced when Canadian troops were deployed to Afghanistan. Previously, a tan version of the olive combats had been used for tropical wear by soldiers deployed to the Middle East, particularly during Operation Desert Storm and were to be worn by the Canadian Airborne Regiment for the deployment the Western Sahara in 1991. They were later worn by the Cdn Ab Regt during their deployment to Somalia. The TAN colored combat uniform was also issued to Canadian troops serving in the Western Sahara with the UN Mission during 1992–1993.
