The United States Marine Corps (USMC) is an independent branch of the US armed forces. The unit was established in November 1775, and the first branch of this unit was formed a year later. In the nineteenth and early twentieth centuries, US Marines served primarily in the region of South and Central America, guarding American interests in this part of the world. It was also then that the principle was established that it was the USMC that was deployed to the area of operations as the first among other units of the US armed forces. Corps soldiers fought in World War I, but they gained special fame in the course of bloody and heavy fights in the Pacific in 1941-1945, taking part in such battles as Guadalcanal (1942-1943), Tarawa (1943), Iwo-Jima and Okinawa (both from 1945). Often in the face of the enemy, the soldiers of this formation showed a lot of courage, an example of which can be, for example, John Basilone was awarded the Medal of Honor for his accomplishment during the battles on the Gudalcanal. After 1945, the soldiers of the Corps fought, for example, in the Korean War (1950-1953) or especially in the Vietnam War (1964 / 1965-1975), suffering heavy losses in the latter war. After the end of the Cold War, USMC soldiers took part in, for example, both Gulf Wars (1990-1991 and 2003). Currently, there are 182,000 soldiers in the Corps, and about 38,500 in the reserve. The motto of the Corps is the Latin motto Semper Fidelis (Polish always faithful).United States Armed Forces ) are currently the most powerful and strongest troops in the world, with an active staff of approximately 1.36 million people and a budget of $ 686 billion in 2018. One of their most important components is the United States Air Force (USAF for short), which is currently considered the strongest and most modern in the world. In 2018, the USAF served approximately 323,000 soldiers and approximately 175,000 civilian employees. At present, the F-22 Raptor and the F-15 Eagle are the basic air superiority fighter. The multi-role fighters include machines such as the F-15E Strike Eagle, F-16 Fighting Falcon or F-35 Lightning II, which will ultimately be the basic multi-role fighter. USAF also has a fleet of strategic bombers consisting of the B-1B, B-2 Spirit and B-52 Stratofortress. The American air force also has a huge fleet of transport machines consisting of machines such as the C-5 Galaxy, C-130 Hercules or C-17 Globemaster III. It can be estimated that the USAF has approximately 5,100 manned aircraft. It is worth adding that USAF pilots - like many other air forces in the world - undergo long training, often lasting several months for fighter pilots. As a result, the cost of training one jet pilot can be counted in millions of dollars!
