The initial assault by North Korean KPA forces were aided by the use of Soviet T-34-85 tanks. A North Korean tank corps equipped with about 120 T-34s spearheaded the invasion. These drove against a ROK Army with few anti-tank weapons adequate to deal with the Soviet T-34s. Additional Soviet armor was added as the offensive progressed. The North Korean tanks had a good deal of early successes against South Korean infantry, elements of the 24th Infantry Division, and those United States built M24 Chaffee light tanks that they encountered. Interdiction by ground attack aircraft was the only means of slowing the advancing Korean armor. The tide turned in favour of the United Nations forces in August 1950 when the North Koreans suffered major tank losses during a series of battles in which the UN forces brought heavier equipment to bear, including M4A3 Sherman medium tanks backed by U.S. M26 heavy tanks, along with the British Centurion, Churchill, and Cromwell tanks.

Because neither Korea had a significant navy, the Korean War featured few naval battles. A skirmish between North Korea and the UN Command occurred on 2 July 1950; the U.S. Navy cruiser USS Juneau, the Royal Navy cruiser HMS Jamaica, and the frigate HMS Black Swan fought four North Korean torpedo boats and two mortar gunboats, and sank them. USS Juneau later sank several ammunition ships that had been present. The last sea battle of the Korean War occurred at Inchon, days before the Battle of Incheon; the ROK ship PC-703 sank a North Korean mine layer in the Battle of Haeju Island, near Inchon. Three other supply ships were sunk by PC-703 two days later in the Yellow Sea. Thereafter, vessels from the UN nations held undisputed control of the sea about Korea. The gun ships were used in shore bombardment, while the aircraft carriers provided air support to the ground forces.

During most of the war, the UN navies patrolled the west and east coasts of North Korea, sinking supply and ammunition ships and denying the North Koreans the ability to resupply from the sea. Aside from very occasional gunfire from North Korean shore batteries, the main threat to United States and UN navy ships was from magnetic mines. During the war, five U.S. Navy ships were lost to mines: two minesweepers, two minesweeper escorts, and one ocean tug. Mines and gunfire from North Korean coastal artillery damaged another 87 U.S. warships, resulting in slight to moderate damage.

The Chinese intervention in late October 1950 bolstered the Korean People's Air Force (KPAF) of North Korea with the MiG-15, one of the world's most advanced jet fighters. The fast, heavily armed MiG outflew first-generation UN jets such as the F-80 (United States Air Force) and Gloster Meteors (Royal Australian Air Force), posing a real threat to B-29 Superfortress bombers even under fighter escort. Fearful of confronting the United States directly, the Soviet Union denied involvement of their personnel in anything other than an advisory role, but air combat quickly resulted in Soviet pilots dropping their code signals and speaking over the wireless in Russian. This known direct Soviet participation was a casus belli that the UN Command deliberately overlooked, lest the war for the Korean peninsula expand to include the Soviet Union, and potentially escalate into atomic warfare.

Questions and answers:

The USAF countered the MiG-15 by sending over three squadrons of its most capable fighter, the F-86 Sabre. These arrived in December 1950. The MiG was designed as a bomber interceptor. It had a very high service ceiling—50,000 feet (15,000 m) and carried very heavy weaponry: one 37 mm cannon and two 23 mm cannons. They were fast enough to dive past the fighter escort of P-80 Shooting Stars and F9F Panthers and could reach and destroy the U.S. heavy bombers. B-29 losses could not be avoided, and the Air Force was forced to switch from a daylight bombing campaign to the necessarily less accurate nighttime bombing of targets. The MiGs were countered by the F-86 Sabres. They had a ceiling of 42,000 feet (13,000 m) and were armed with six .50 caliber (12.7 mm) machine guns, which were range adjusted by radar gunsights. If coming in at higher altitude the advantage of engaging or not went to the MiG. Once in a level flight dogfight, both swept-wing designs attained comparable maximum speeds of around 660 mph (1,100 km/h). The MiG climbed faster, but the Sabre turned and dived better.

Q: What plane did the US send to Korea to counter the power of the MiG-15?

In February 1907, the Royal Dutch Shell Group was created through the amalgamation of two rival companies: the Royal Dutch Petroleum Company of the Netherlands and the "Shell" Transport and Trading Company Ltd of the United Kingdom. It was a move largely driven by the need to compete globally with Standard Oil. The Royal Dutch Petroleum Company was a Dutch company founded in 1890 to develop an oilfield in Sumatra, and initially led by August Kessler, Hugo Loudon, and Henri Deterding. The "Shell" Transport and Trading Company (the quotation marks were part of the legal name) was a British company, founded in 1897 by Marcus Samuel, 1st Viscount Bearsted, and his brother Samuel Samuel. Their father had owned an antique company in Houndsditch, London, which expanded in 1833 to import and sell sea-shells, after which the company "Shell" took its name.

For various reasons, the new firm operated as a dual-listed company, whereby the merging companies maintained their legal existence, but operated as a single-unit partnership for business purposes. The terms of the merger gave 60 percent ownership of the new group to the Dutch arm and 40 percent to the British. National patriotic sensibilities would not permit a full-scale merger or takeover of either of the two companies. The Dutch company, Koninklijke Nederlandsche Petroleum Maatschappij, was in charge at The Hague of production and manufacture. A British company was formed, called the Anglo-Saxon Petroleum Company, based in London, to direct the transport and storage of the products.

The presence of companies like Shell in the Niger-Delta has led to extreme environmental issues in the Niger Delta. Many pipelines in the Niger-Delta owned by Shell are old and corroded. Shell has acknowledged its responsibility for keeping the pipelines new but has also denied responsibility for environmental causes. This has led to mass protests from the Niger-Delta inhabitants and Amnesty International against Shell and Friends of the Earth Netherlands. It has also led to action plans to boycott Shell by environmental groups, and human rights groups. In January 2013, a Dutch court rejected four out of five allegations brought against the firm over oil pollution in the Niger Delta but found a subsidiary guilty of one case of pollution, ordering compensation to be paid to a Nigerian farmer.

The name Shell is linked to The "Shell" Transport and Trading Company. In 1833, the founder's father, Marcus Samuel, founded an import business to sell seashells to London collectors. When collecting seashell specimens in the Caspian Sea area in 1892, the younger Samuel realised there was potential in exporting lamp oil from the region and commissioned the world's first purpose-built oil tanker, the Murex (Latin for a type of snail shell), to enter this market; by 1907 the company had a fleet. Although for several decades the company had a refinery at Shell Haven on the Thames, there is no evidence of this having provided the name.

Shell's primary business is the management of a vertically integrated oil company. The development of technical and commercial expertise in all stages of this vertical integration, from the initial search for oil (exploration) through its harvesting (production), transportation, refining and finally trading and marketing established the core competencies on which the company was founded. Similar competencies were required for natural gas, which has become one of the most important businesses in which Shell is involved, and which contributes a significant proportion of the company's profits. While the vertically integrated business model provided significant economies of scale and barriers to entry, each business now seeks to be a self-supporting unit without subsidies from other parts of the company.

Traditionally, Shell was a heavily decentralised business worldwide (especially in the downstream) with companies in over 100 countries, each of which operated with a high degree of independence. The upstream tended to be far more centralised with much of the technical and financial direction coming from the central offices in The Hague. Nevertheless, there were very large "exploration and production" companies in a few major oil and gas production centres such as the United Kingdom (Shell Expro, a Joint Venture with Exxon), Nigeria, Brunei, and Oman.

Downstream operations, which now also includes the chemicals business, generates a third of Shell's profits worldwide and is known for its global network of more than 40,000 petrol stations and its 47 oil refineries. The downstream business, which in some countries also included oil refining, generally included a retail petrol station network, lubricants manufacture and marketing, industrial fuel and lubricants sales and a host of other product/market sectors such as LPG and bitumen. The practice in Shell was that these businesses were essentially local and that they were best managed by local "operating companies" – often with middle and senior management reinforced by expatriates. In the 1990s, this paradigm began to change, and the independence of operating companies around the world was gradually reduced. Today, virtually all of Shell's operations in various businesses are much more directly managed from London and The Hague. The autonomy of "operating companies" has been largely removed, as more "global businesses" have been created.
