The U.S. military and armed forces are made up of five different branches. They are the Army, the Air Force, the Marines, the Navy and the Coast Guard. Each is a separate subdivision with different duties and training.

1. World War II
   Korean War
2. World War I
   Civil War

While is wasn't the largest war in terms of scale, no war cost more American lives than the Civil War. This makes sense, as the fighting took place on U.S soil and only involved Americans. In total, 620,000-750,000 Americans died as a result of the war.

In 1947, a unified National Military Establishment was founded. However, after only two years, it was renamed the Department of Defense. Currently, the department is the largest employer on the planet.

1. Around 16,000,000
   Around 800,000
2. Around 7,650,000
   Around 1,250,000

The sheer size and participation in World War II are what make it one of the most massive and famous conflicts in world history. The USA contributed to that when they had over 16,000,000 people serve in the war.

That's right, the USA has only formally declared war 11 times in five different wars. The first time they declared was 1812, and the last time they did so was back in 1942 as a part of World War II.

The Army of the USA has been around for a very long time. It was founded way back on June 14th, 1775, which means it was around before the USA officially gained independence. The Army is headquartered at the Pentagon in Virginia.

The draft (or conscription) is when people are required to enlist in the armed services. The USA has only used conscription in five different battles or conflicts and doesn't utilize it anymore.

1. General of the Armies
   Military Commander
2. Fleet Admiral
   Five-star commander

There are many different ranks in the U.S. Army, each with a different level of seniority. There is no higher rank than the General of the Armies. As mentioned, only two different people have held this rank: George Washington and John J. Pershing.

While there are now a ton of women serving in the U.S. military, this wasn't always the case. Loretta Walsh became the very first woman to serve in the military in a role other than a nurse, and that was way back in 1917.

1. Andrew Jackson
   Woodrow Wilson
2. John Adams
   Thomas Jefferson

Before Andrew Jackson became the President of the USA in 1829 until 1837, he was a general in the War of 1812. In addition to that, he also served in the Congress, in both houses.

1. New Mexico

The very first state to secede from the Union was South Carolina; they did so on December 20th, 1860. The Civil War began when secessionist forces attacked a military fort in South Carolina.

1. New Mexico
   Texas
2. Virginia
   Louisiana

In 1845, Texas went through annexation and was brought into the United States of America. With this not being formally recognized by the Mexican government, a war began between Mexico and the USA, which went from 1846 to 1848.

1. Over 200,000,000
   Around 6,500,000
2. Over 70,000,000

Of all the wars and conflicts on the planet, none have been as deadly as World War II. The war cost the lives of between 70-85 million people around the world. At the time, that was about 3% of the entire world's population.

1. Pearl Harbor
   Fear of German hegemony
2. An attack on American tourists
   They were paid to do so

Before (and during the early stages of) World War I, the USA had wanted to stay out of military conflicts. However, after a growing fear of German aggression, the USA decided to enter World War I in late 1917.

1. Central America and the Caribbean
   Russia
2. Antarctica

Many military awards and decorations can be awarded to soldiers for a job well done or to recognize an achievement. However, none are more prestigious than the Medal of Honor, which is typically awarded by the President of the USA. Here, United States Navy submarine sailor Henry Breault receives the Medal of Honor from President Calvin Coolidge.

1. Japan
   Soviet Union
2. Canada
   France

The Cold War took place across many decades between the USA and the Soviet Union. While no military campaigns directly took place, the war cost millions of lives and a ton of money on both sides.

1. George Washington
   Christopher Columbus
2. Abraham Lincoln
   Theodore Roosevelt

In addition to being the first-ever President of the USA, George Washington was also the Commander-in-Chief of the Continental Army. The role was originally created to coordinate the war efforts of the Thirteen Colonies.

While women have been involved in wars for a while, they were either nurses, cooks or other non-combat positions, or they had to pretend to be men. But in 1948, women were given permanent status as regular soldiers.

The Vietnam war lasted almost 20 years and left multiple millions of people dead. While the war didn't officially end until 1975, the USA ended its involvement in the war a few years sooner in 1973.

The War on Terror began as soon as Al-Qaeda attacked the World Trade Centers and other landmarks on September 11th, 2001. In total, nearly 3,000 civilians died, which makes it the most deadly terrorist attack in U.S. history.

While the military has a minimum age of 18 to join and serve, some people younger than that have managed to fool them. The youngest of them all was Calvin Graham, shown here, who actually enlisted at the age of 12.

   Abu Sayyaf
2. Boko Haram
   Islamic State of Iraq and Syria

Over the past few years, ISIS has been one of the largest terrorist threats on the planet. It has been responsible for many large and violent attacks across the planet and has killed numerous individuals. The ISIS flag shown here is also used by al-Shabaab, al-Qaeda in the Arabian Peninsula (AQAP), al-Qaeda in the Islamic Maghreb (AQIM), and Boko Haram.

2. Neutrality Acts of the 1930s
   War Ban of 1931

There was growing turmoil in Europe and Asia throughout the 1930s that ultimately led to World War II. The USA developed the Neutrality Acts of 1930 to ensure that they didn't become involved in foreign conflicts, but it was short-lived. After the Japanese attack on Pearl Harbor in 1941, shown here, the acts were largely repealed.

The USA is nearly 250 years old and has been at war for over 220 of those years. This means the country has only been at peace for a small minority of the time it has officially been a country.
