The United States Marine Corps (USMC) is a branch of the United States Armed Forces responsible for providing power projection from the sea, using the mobility of the United States Navy to deliver combined-arms task forces rapidly. It is one of seven uniformed services of the United States. In the civilian leadership structure of the United States military, the Marine Corps is a component of the United States Department of the Navy, often working closely with U.S. naval forces for training, transportation, and logistic purposes; however, in the military leadership structure the Marine Corps is a separate branch.

Captain Samuel Nicholas formed two battalions of Continental Marines on 10 November 1775 in Philadelphia as naval infantry. Since then, the mission of the Marine Corps has evolved with changing military doctrine and American foreign policy. The Marine Corps has served in every American armed conflict and attained prominence in the 20th century when its theories and practices of amphibious warfare proved prescient and ultimately formed the cornerstone of the Pacific campaign of World War II. By the mid-20th century, the Marine Corps had become the dominant theorist and practitioner of amphibious warfare. Its ability to rapidly respond on short notice to expeditionary crises gives it a strong role in the implementation and execution of American foreign policy.

The United States of America (commonly abbreviated to the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity). Per capita income is the world's sixth-highest.

Carly Rae Jepsen (born November 21, 1985) is a Canadian recording artist and singer-songwriter from Mission, British Columbia. In 2007, she placed third in the fifth season of Canadian Idol, and was a part of the Canadian Idol Top 3 concert tour.

Shortly after competing on Idol, she signed to Fontana and MapleMusic, and released her debut album, Tug of War, on September 30, 2008. Three years later, she released a new single, entitled "Call Me Maybe", which was released by 604 Records, and was followed by the release of her debut extended play, Curiosity, on February 14, 2012. "Call Me Maybe" was met with much success, reaching the Top 5 on the Billboard Hot 100 and reaching the number 1 spot on the Canadian Hot 100. The single also went to number 1 in Australia, Ireland and the United Kingdom. Jepsen signed with Interscope Records in 2012.

Jepsen attended Heritage Park Secondary School in Mission, British Columbia and has since performed there post-graduation. She later attended the Canadian College of Performing Arts in Victoria, BC before auditioning for Canadian Idol. After completing the Canadian Idol tour, Jepsen retreated to B.C. to focus on writing, recording and completing her band. Her demos attracted attention and she was eventually signed a joint management deal with Simkin Artist Management and Dexter Entertainment. A deal with Fontana/Maple Music quickly followed, leading Jepsen into the studio with producer/writer Ryan Stewart.

The United States Marine Drum and Bugle Corps is the drum and bugle corps of the United States Marine Corps. The D&B is now the only full time active duty drum corps in the United States Armed Forces. As one of many United States military bands, the United States Marine Drum and Bugle Corps consists of 80 active-duty Marines dressed in ceremonial red and white uniforms. The D&B performs martial and popular music.

The United States Marine Drum and Bugle Corps has been officially designated as "The Commandant's Own" because of its historical connection with the Commandant of the Marine Corps. The D&B is entirely separate from its sister military band, the United States Marine Band "The President's Own" as well as the 12 active-duty United States Marine Corps field bands. The United States Marine Drum and Bugle Corps travels more than 50,000 miles (80,000 km) annually, performing in excess of 400 events across the United States and around the world.

During the summer months, the D&B performs in conjunction with "The President's Own" in the traditional Friday Evening Parades at the Marine Barracks Washington and in the Sunset Parades at the Marine Corps War Memorial (Iwo Jima Monument) in Arlington, Virginia, every Tuesday evening. The parades are not street parades, but military parades consisting of ceremonial pomp that are symbolic of Marine professionalism, discipline, and esprit de corps.
