The US Army
The United States Army is the land component of the U.S. Armed Forces responsible for providing trained and disciplined forces to defend America, unless ordered to do otherwise. The army has provided more than 80% of all personnel who have served in the armed forces since its inception in 1775 and today serves as a ground combat force with marine, air and cavalry components.
The United States Army is the ground-based service branch of the U.S. Armed Forces and the principal land warfare force.
Established by Congress by the National Security Act of July 29, 1947, it was a result of the recommendations of General Douglas MacArthur and provides for peacetime and wartime missions for assigned forces. The United States Army is one of the five branches of the United States Armed Forces. As the oldest and largest branch of the armed services, it engages in military operations worldwide and is one of two U.S. military services that has been involved in every U.S. war from 1776 to the present day.
The Army was founded in 1775 by Timothy Pickering to defend the nation against a British Navy invasion during the Revolutionary War.
It played a central role in many of the decisive battles of the war and made great strides toward national independence. The Army fought numerically superior forces alongside Continental regiments and was responsible for defending key points on the coast and inland waterways which provided vital strategic advantages over Britain’s naval blockade.
The Continental Army faced several crises that threatened its survival, including internal disputes, lack of funding, and leadership problems, caused in part by George Washington’s lack of military experience.
There were several crises that threatened the survival of the Continental Army. The biggest was lack of funding, followed by poor leadership and, then, losing battle after battle against the British. The Continental Army was a force of 13,000 to 20,000 men that served in defense of the Thirteen Colonies that revolted against Great Britain during the American Revolutionary War (1775–1783). After victory in the Battle of Saratoga in 1777 and the October 1778 Battle at Kip’s Bay, they were defeated by British General Clinton at New York City on November 16th, 1781. Their defeat left America unprepared to defend itself from Great Britain which would eventually bring about new peace terms and end the War for Independence.

Ulysses S. Grant – The White House
During the American Civil War, General Ulysses S. Grant led Union army to victory over Confederate forces at Vicksburg after a series of battles and then he defeated Robert E. Lee’s army at Appomattox in April 1865.
When the American Civil War broke out, there were two main objectives for both sides. On one hand, Abraham Lincoln wanted to preserve the Union and put an end to slavery but on the other hand, the Confederate states wanted to keep their slaves and not allow any federal control over them. After several battles both Lincoln and General Ulysses S. Grant were able to raise enough troops to defeat the Confederate forces at Vicksburg and then they won at Appomattox Courthouse which marked the end of the American Civil War.
Many basic tactics such as fire-and-maneuver, fire support, combined arms warfare were developed by the Army before World War II in order to fight against Germany’s Wehrmacht.
The US Army’s tactics were developed in two ways. One way was through the development of doctrine, which is the way of interpreting and applying the knowledge and skills necessary to conduct military operations. Doctrine assists in distilling complex concepts into simple, easily communicated units of information. The other way is by actions taken in support of doctrine, such as training and exercises.

Western Allied invasion of Germany
In 1943, the German Army was defeated by Allied forces in Tunisia and Sicily before being defeated again on mainland Italy by February 1944.
On October 11, 1943, the German Army was defeated by Allied forces in North Africa and Sicily. The encounter in North Africa occurred at Kasserine Pass in Tunisia. The Germans were forced to retreat to the island of Sicily, where they were steadily pushed back until they surrendered on May 5th, 1945. The battle was one of the most significant battles of World War II as it prevented German intentions to invade Egypt and endanger British supply lines through Suez Canal.
On November 8, 1941, Germany invaded the Soviet Union from three directions but they could not capture Moscow despite their huge effort and they lost
On November 8, 1941, the attacked started and they attacked Moscow not only with infantry but also with tanks, aircraft and trains. As Germany lost more territory after losing battles of Stalingrad and Kursk, they started to lose the war at least three months before they could capture Moscow. Germany invaded the Soviet Union from three directions but they could not capture Moscow despite their huge effort and they lost the battle of Moscow. The popular saying is, “Russia Will Be Ready.” It is a source of power for the whole country.
