3rd Battalion 6th Marines is an infantry battalion in the United States Marine Corps based out of Camp Lejeune, North Carolina. Also known as Teufelhunden, it consists of approximately 300 Marines and they fall under the 6th Marine Regiment and the 2nd Marine Division. H&S Company Mike Company India Company Kilo Company Lima Company Weapons Company 3rd Battalion 6th Marines was activated on August 14,1917 at Quantico, Virginia as the 3rd Battalion and they were quickly deployed during October–November 1917 to France and assigned to the 4th Brigade, American Expeditionary Force. They participated in the following World War I offensive campaigns, Aisne-Marne, St. Mihiel and they also participated in the following World War I defensive campaigns, Toulon-Troyon, Chateau-Thiery, Marabache, and Limey. Following the war took part in the occupation of the Rhineland.

They participated in maneuvers at Gettysburg, Pennsylvania, June–July 1922 and they moved during January 1925 to Quantico, Virginia and were again deactivated February 1,1925. Reactivated April 1927 at Norfolk, Virginia as the 3rd Battalion, 6th Regiment and they deployed during April–July 1927 to Tientsin, China and reassigned to the 3rd Marine Brigade. The Battalion was redesignated October 4,1927 as the 1st Battalion,12 Regiment and redesignated again on April 22,1928 as the 3rd Battalion, in October 1928 they moved to San Diego, California and were deactivated November 10,1928. 3/6 was again reactivated on November 1,1940 in San Diego, California as the 3rd Battalion, 6th Marines, in the spring of 1941 they deployed to Reykjavík, Iceland and were reassigned to the 1st Provisional Marine Brigade. They returned January–February 1942 to San Diego, California and reassigned to the 2nd Marine Division, deployed during October–November 1942 to Wellington, New Zealand they participated in the following World War II campaigns, Guadalcanal, Southern Solomons, Tarawa, Saipan, Tinian and Okinawa. Following the war they were relocated during September 1945 to Nagasaki and they participated in the Occupation of Japan, September 1945 to February 1946 and arrived back in Camp Pendleton, California during February–March 1946. They were again deactivated March 27,1946, 3/6 was again brought back on October 17,1949 on board USS Fremont and assigned to the 2nd Marine Division. The battalion relocated during August 1950 to Camp Pendleton, California, 3/6 was quickly reactivated September 12,1950 at Camp Lejeune, North Carolina and assigned to the 2nd Marine Division. During this time assisted in the capture and defense of Kandahar Airfield. In March 2004 the battalion resumed their function as an infantry battalion, in August 2005, 3/6 made their first deployment to Iraq in support of Operation Iraqi Freedom. They returned from Iraq in late March 2006 having served in the Al-Anbar province in the Al-Qaim region, in October 2005, the battalion performed Operation Ironfist and successfully swept and cleared the cities of Sadah and Eastern Karabilah taking minimal casualties. They also operated as the effort under RCT-2 alongside 2nd Battalion 1st Marines during Operation Steel Curtain during which they raided, swept

Time signature
–
The time signature is a notational convention used in Western musical notation to specify how many beats are to be contained in each bar and which note value is to be given one beat. A mid-score time signature, usually following a barline, indicates a change of meter. | Simple time signatures consist of two numerals, one stacked above the other, The lower numeral indicates the value that represents one beat. The upper numeral indicates how many beats there are grouped together in a bar. For instance,24 means two quarter-note beats per bar—38 means three eighth-note beats per bar, the most common simple time signatures are 24,34, and 44. The symbol is used for 44 time, also called common time or imperfect time. In modern notation, it is used in place of 22 and is called alla breve or, colloquially, in compound meter, subdivisions of the main beat are in three equal parts, so that a dotted note becomes the beat unit. Compound time signatures are named as if they were simple time signatures, in which the part of the beat unit is the beat. The lower number is most commonly an 8, as in 98 or 128,34 is a simple signature that represents three quarter notes. To the ear, a bar may seem like one singular beat, for example, a fast waltz, notated in 34 time, may be described as being one in a bar. Terms such as quadruple, quintuple, and so on are also occasionally used, as mentioned above, though the score indicates a 34 time, the actual beat division can be the whole bar, particularly at faster tempos. Correspondingly, at slow tempos the beat indicated by the time signature could in actual performance be divided into smaller units, on a formal mathematical level the time signatures of, e. g.34 and 38 are interchangeable. In a sense, all simple triple time signatures, such as 38,34,32, etc. —and all compound duple times, such as 68,616, a piece in 34 can be easily rewritten in 38, simply by halving the length of the notes. Other time signature rewritings are possible, most commonly a simple time signature with triplets translates into a compound meter, though formally interchangeable, for a composer or performing musician, different time signatures often have different connotations. First, a note value in the beat unit implies a more complex notation. Second, beaming affects the choice of actual beat divisions and it is, for example, more natural to use the quarter note/crotchet as a beat unit in 64 or 22 than the eight/quaver in 68 or 24. Third, time signatures are traditionally associated with different music styles—it might seem strange to notate a rock tune in 48 or 42. For all meters, the first beat is stressed, in time signatures with four groups in the bar

Fraction (mathematics)
–
A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction consists of an integer numerator displayed above a line, numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals. The numerator represents a number of parts, and the denominator. For example, in the fraction 3/4, the numerator,3, tells us that the fraction represents 3 equal parts, the picture to the right illustrates 34 or ¾ of a cake. Fractional numbers can also be written without using explicit numerators or denominators, by using decimals, percent signs, an integer such as the number 7 can be thought of as having an implicit denominator of one,7 equals 7/1. Other uses for fractions are to represent ratios and to represent division, thus the fraction ¾ is also used to represent the ratio 3,4 and the division 3 ÷4. The test for a number being a number is that it can be written in that form. In a fraction, the number of parts being described is the numerator. Informally, they may be distinguished by placement alone but in formal contexts they are separated by a fraction bar. The fraction bar may be horizontal, oblique, or diagonal and these marks are respectively known as the horizontal bar, the slash or stroke, the division slash, and the fraction slash. In typography, horizontal fractions are known as en or nut fractions and diagonal fractions as em fractions. The denominators of English fractions are expressed as ordinal numbers. When the denominator is 1, it may be expressed in terms of wholes but is commonly ignored. When the numerator is one, it may be omitted, a fraction may be expressed as a single composition, in which case it is hyphenated, or as a number of fractions with a numerator of one, in which case they are not. Fractions should always be hyphenated when used as adjectives, alternatively, a fraction may be described by reading it out as the numerator over the denominator, with the denominator expressed as a cardinal number. The term over is used even in the case of solidus fractions, Fractions with large denominators that are not powers of ten are often rendered in this fashion while those with denominators divisible by ten are typically read in the normal ordinal fashion. A simple fraction is a number written as a/b or a b
