Belfer also shared that she plans on continuing research in this area. Specifically, fair-eyed folks are more at risk of developing melanoma of the uvea (that's the middle layer of your eye) than their brown-eyed counterparts. Accidental fire not intended to attack the enemy, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire,[1] and neither is unintentional harm to civilians or structures, which is sometimes referred to as collateral damage.

But there is a science behind why men get this uncomfortable feeling and why it's been labeled as such. Although having blue eyes (or light-colored eyes) is considered quite beautiful, there is one disadvantage that comes along with this phenotype. Finally, at places nine and ten are the United States and Spain, both with just over 16 percent of the population possessing cerulean eyes. Jon Krakauer provides an overview of American casualties during and since the Second World War: While acknowledging that the "statistical dimensions of the friendly fire problem have yet to be defined; reliable data are simply not available in most cases," The Oxford Companion to American Military History estimates that between 2 percent and 2.5 percent of the casualties in America's wars are attributable to friendly fire.[7]. England is next on the list with 48 percent, while 45 percent of people in Wales have baby blues. Correct navigation is vital to ensuring units know where they are in relation to their own force and the enemy. [10], Friendly fire arises from the "fog of war" – the confusion inherent in warfare. "They have all inherited the same switch at exactly the same spot in their DNA." Blue light is usually referred to as radiation with wavelengths between 400 and 500 nm. Incidents range from the killing of Royalist commander, the Earl of Kingston, by Royalist cannon fire during the English Civil War,[22] the bombing of American troops by Eighth Air Force bombers during Operation Cobra in World War II,[23] the eight-hour firefight between British units during the Cyprus Emergency,[24] the downing of a British helicopter by a British warship during the Falklands War,[25] the shooting of two U.S. Army Black Hawk helicopters by USAF fighters in 1994 during the Iraqi no-fly zones,[26] the killing of a Royal Military Policeman by a British sniper during the war in Afghanistan,[27] and the Tarnak Farm incident when US Air National Guard pilots in 2002 bombed 12 Canadian soldiers, four of whom were killed;[28] these were the first Canadian casualties of the war in Afghanistan. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Invasion stripes served a similar function during the Allied invasion of Normandy in World War II. In the 1991 Gulf War, most of the Americans killed by their own forces were crew members of armored vehicles hit by anti-tank rounds. [12][13] Another case of such an accident was the death of Pat Tillman in Afghanistan, although the exact circumstances of that incident are yet to be definitively determined.[14]. Late in the war the "protection squadron" that covered the elite German jet fighter squadron as it landed or took off were brightly painted to distinguish them from raiding Allied fighters. Similar markings had been used when the Hawker Typhoon was first introduced into use as it was otherwise very similar in profile to a German aircraft. How does it work? [21], The shock and awe battle tactics adopted by the American military – overwhelming power, battlefield awareness, dominant maneuvers, and spectacular displays of force – are employed because they are believed to be the best way to win a war quickly and decisively, reducing casualties on both sides.

Normally blue moons come only about every two or three years. But you can always tell the difference between a natural blue and an artificial blue — it's a pretty hard color to fake. Other technological changes include hand-held navigational devices that use satellite signals, giving ground forces the exact location of enemy forces as well as their own. That's why you can't know what someone's eye color will be when they grow up until about the six-month mark, according to an article published by McGill University. Of course, plenty of folks who don't have blue eyes can fake it with contacts, as celebs like Selena Gomez and Nicki Minaj have done on occasion. That's unlike brown-eyed folks, who have significant differences in their DNA related to melanin production. One is called the kernel mode and the other one user mode. There's a reason blue eyes appear to change color, which is related to why they look blue in the first place. That's a lot! cites a 1925 reference to a term used in trenches during the war, Claire Outteridge, Simon Henderson, Raphael Pascual, Paul Shanahan, "How can Human Factors be Exploited to Reduce the Risk of Fratricide?" The reason that many babies are born with blue eyes that can later change to brown is, once again, due to the way melanin functions in the human body. By the 20th and 21st centuries, friendly-fire casualties have likely become a significant percentage of combat injuries and fatalities. According to a study published in the journal Behavioral Ecology and Sociobiology, blue-eyed men find blue-eyed women more attractive than women with any other eye color.

When a baby is born, melanin hasn't yet been fully deposited into the iris of the child's eye, which results in the iris being blue. Tactical adjustments include the use of "kill boxes", or zones that are placed off-limits to ground forces while allied aircraft attack targets, which goes back to the beginning of military aircraft in World War I. It's part of a larger pattern: the temptation among generals and politicians to control how the press portrays their military campaigns, which all too often leads them to misrepresent the truth in order to bolster public support for the war of the moment.

Although there are a ton of actors, models, and other celebs who have blue eyes, which can make these colored eyes seem like a common asset (at least on television), not all that many people are lucky enough to boast baby blues. [2] Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting.[3].

To be fair, people with green and hazel eyes are also prone to seemingly color-changing irises as well, so this isn't unique to blue-eyed folks. There is also some development of remote sensors to detect enemy vehicles – the Remotely Monitored Battlefield Sensor System (REMBASS) uses a combination of acoustic, seismic vibration, and infrared to not just detect, but identify vehicles. The reason the second definition of Blue Moon exists is due to an error originally made by amateur astronomer James Hugh Pruett (18861955).

Radios, field telephones, and signalling systems can be used to address the problem, but when these systems are used to co-ordinate multiple forces such as ground troops and aircraft, their breakdown can dramatically increase the risk of friendly fire.
