Marine Aircraft Group 14
Marine Aircraft Group 14 (MAG-14) is a United States Marine Corps aviation unit based at Marine Corps Air Station Cherry Point, North Carolina that is currently composed of four AV-8B Harrier squadrons, four EA-6B Prowler squadrons, one KC-130 squadron, a maintenance and logistics squadron, and a wing support squadron.
Mission
Conduct offensive air support, anti-air warfare, electronic warfare, assault support, and air reconnaissance operations in support of the Marine Air-Ground Task Force or joint and coalition forces, and conduct fleet replacement program training in order to provide combat capable aircrews to operational squadrons.

History
World War II
Marine Aircraft Group 14 was formed at then Camp Kearny, California on 1 March 1942. The nucleus for the new aircraft group came from Marine Aircraft Group 11 which had just arrived from Marine Corps Air Station Quantico following the 7 December 1941 attack on Pearl Harbor. They remained there training until they deployed for the Pacific Theater in October 1942. The Group soon arrived at Guadalcanal relieving Marine Aircraft Group 23 on 16 October 1942 to become part of the Cactus Air Force. The group would take part in the Battle of the Santa Cruz Islands just 10 days later. In November 1942 they took part in the Naval Battle of Guadalcanal and continued to fight in the skies over the island until 4 April 1943 when they were sent to Auckland, New Zealand to rest and refit.
Carbon group
The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
In modern IUPAC notation, it is called Group 14. In the field of semiconductor physics, it is still universally called Group IV. The group was once also known as the tetrels (from Greek tetra, four), stemming from the Roman numeral IV in the group names, or (not coincidentally) from the fact that these elements have four valence electrons (see below). The group is sometimes also referred to as tetragens or crystallogens.
Characteristics
Chemical
Like other groups, the members of this family show patterns in electron configuration, especially in the outermost shells, resulting in trends in chemical behavior:
Each of the elements in this group has 4 electrons in its outer orbital (the atom's top energy level). The last orbital of all these elements is the p2 orbital. In most cases, the elements share their electrons. The tendency to lose electrons increases as the size of the atom increases, as it does with increasing atomic number. Carbon alone forms negative ions, in the form of carbide (C4−) ions. Silicon and germanium, both metalloids, each can form +4 ions. Tin and lead both are metals while flerovium is a synthetic, radioactive (its half life is very short), element that may have a few noble gas-like properties, though it is still most likely a post-transition metal. Tin and lead are both capable of forming +2 ions.
