308th Infantry Division (Vietnam)
The 308th Infantry Division is a division of the People's Army of Vietnam (PAVN), first formed in August 1950 in southern China from the previous Regimental Group 308. History First Indochina War As early as January 1946, the first regiment of the PAVN, the 102 'Capital' Regiment, was created for operations around Hanoi. It consisted of Regiments 88, 102, and 36, and soon became the 308 'Vanguard' Division. By late 1950 the 308 Division had a full three infantry regiments, one heavy weapons regiment, and support units. The 308th initiated the Battle of Vĩnh Yên with an attack on Groupe Mobile 3 on the evening of 13 January 1951, surrounding and half-destroying the unit. The 308th and 312th then surrounded Vĩnh Yên. The French counterattacked and began to airlift reinforcements into Vĩnh Yên. On 16 August the 308th and 312th launched human wave attacks against the French positions which were largely repulsed by French ground fire and airstrikes. At dawn on 17 January the Vi ...

Second Battle Of Quảng Trị
The Second Battle of Quang Tri ( vi, Trận Thành cổ Quảng Trị; also called Operation Lam Sơn 72) began on 28 June 1972 and lasted 81 days until 16 September 1972, when South Vietnam's Army of the Republic of Vietnam defeated the North Vietnamese People's Army of Vietnam at the ancient citadel of Quảng Trị ( vi, Thành cổ Quảng Trị) and recaptured most of Quảng Trị Province. Background During the initial phase of the Easter Offensive the PAVN quickly captured Quảng Trị in the First Battle of Quảng Trị (30 March – 2 May 1972) and overran all of Quảng Trị Province and the north of Thừa Thiên Province.

18th Signal Battalion
18 (eighteen) is the natural number following 17 and preceding 19. In mathematics * Eighteen is a composite number, its divisors being 1, 2, 3, 6 and 9. Three of these divisors (3, 6 and 9) add up to 18, hence 18 is a semiperfect number. Eighteen is the first inverted square-prime of the form ''p''·''q''2. * In base ten, it is a Harshad number. * It is an abundant number, as the sum of its proper divisors is greater than itself (1+2+3+6+9 = 21). It is known to be a solitary number, despite not being coprime to this sum. * It is the number of one-sided pentominoes. * It is the only number where the sum of its written digits in base 10 (1+8 = 9) is equal to half of itself (18/2 = 9). * It is a Fine number. In science Chemistry * Eighteen is the atomic number of argon. * Group 18 of the periodic table is called the noble gases. * The 18-electron rule is a rule of thumb in transition metal chemistry for characterising and predicting the stability of metal complexes. ...

17th Combat Engineer Battalion
17 (seventeen) is the natural number following 16 and preceding 18. It is a prime number. Seventeen is the sum of the first four prime numbers. In mathematics 17 is the seventh prime number, which makes seventeen the fourth super-prime, as seven is itself prime. The next prime is 19, with which it forms a twin prime. It is a cousin prime with 13 and a sexy prime with 11 and 23. It is an emirp, and more specifically a permutable prime with 71, both of which are also supersingular primes. Seventeen is the sixth Mersenne prime exponent, yielding 131,071. Seventeen is the only prime number which is the sum of four consecutive primes: 2, 3, 5, 7. Any other four consecutive primes summed would always produce an even number, thereby divisible by 2 and so not prime. Seventeen can be written in the form x^y + y^x and x^y - y^x, and, as such, it is a Leyland prime and Leyland prime of the second kind: :17=2^+3^=3^-4^. 17 is one of seven lucky numbers of Euler which produc ...

16th Anti-Air Battalion
16 (sixteen) is the natural number following 15 and preceding 17. 16 is a composite number, and a square number, being 42 = 4 × 4. It is the smallest number with exactly five divisors, its proper divisors being , , and . In English speech, the numbers 16 and 60 are sometimes confused, as they sound very similar. Sixteen is the fourth power of two. For this reason, 16 was used in weighing light objects in several cultures. The British have 16 ounces in one pound; the Chinese used to have 16 ''liangs'' in one ''jin''. In old days, weighing was done with a beam balance to make equal splits. It would be easier to split a heap of grains into sixteen equal parts through successive divisions than to split into ten parts. Chinese Taoists did finger computation on the trigrams and hexagrams by counting the finger tips and joints of the fingers with the tip of the thumb. Each hand can count up to 16 in such manner. The Chinese abacus uses two upper beads to represent the 5s and 5 low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

15 (fifteen) is the natural number following 14 and preceding 16. Mathematics 15 is: * A composite number, and the sixth semiprime; its proper divisors being , and . * A deficient number, a smooth number, a lucky number, a pernicious number, a bell number (i.e., the number of partitions for a set of size 4), a pentatope number, and a repdigit in binary (1111) and quaternary (33). In hexadecimal, and higher bases, it is represented as F. * A triangular number, a hexagonal number, and a centered tetrahedral number. * The number of partitions of 7. * The smallest number that can be factorized using Shor's quantum algorithm. * The magic constant of the unique order-3 normal magic square. * The number of supersingular primes. Furthermore, * 15 is one of two numbers within the ''teen'' numerical range (13-19) not to use a single-digit number in the prefix of its name (the first syllable preceding the ''teen'' suffix); instead, it uses the adjective form of five (''fi ...
