In its early years, the United States was a country that wanted nothing to do with armed conflicts outside its own borders. After the two great world wars, however, history forever changed the country’s attitude towards its role in the world, finally becoming a nation that proactively keeps an eye on global threats and stays on top of them (Mawdsley, E., 2019).

While the Pacific and European theatres of war extremely tested the military capabilities of the United States (Klein, 2020), the Cold War further stretched its ability to defend its intelligence capability and political philosophy in the face of the global communist threat posed by China and USSR. Post-Cold War and into modern times, the United States had to grapple with Russia and the quickly rising China (“Elements of the China Challenge, pp. 17-27). In the midst of all these developments, the major U.S. military bases and installations domestic and overseas remain at the forefront of the country’s twin principles: deterrence and reassurance (Frederick, Watts, Lane, Doll, Rhoades, & Smith, 2020).

U.S. Military Bases and Installations – Domestic

Based on such factors as military equipment firepower, manpower, logistics, finance, and natural resources, the U.S. has consistently placed on top of the global firepower rankings since 2005, the year such rankings started.

Looking at the military spending of countries all over the world, it is easy to see why: the U.S. simply outspends every country on the list, spending almost triple its nearest competitor, China. More tellingly, the U.S. actually spends more than the next top ten countries combined.

With the combined power of its economy, population, natural resources, vast territory, and advanced industries, the U.S. successfully rallied its people and allies through World Wars I and II. After the breakup of the U.S.S.R. that brought the Cold War to a close, the U.S. emerged as the only true superpower of the world. The U.S. has assumed the role of the global police since then, a viewpoint that supported its continued maintenance of military bases and installations both domestic and overseas.

With that in mind, we look at the U.S. military bases around the world in 2021, starting with the largest U.S. military bases that are strategically spread among its domestic territories.

1. Nellis Air Force Range

Nellis Air Force Range

State: Nevada

Service Branch: Air Force

Physical Size: 4,531.25 square miles (2.9 million acres) of land, 5,000 square miles of airspace, which is restricted from civilian air traffic over-flight, and another 7,000 square miles of Military Operating Area, or MOA, which is shared with civilian aircraft. The 12,000-square-nautical mile range provides a realistic arena for operational testing and training of aircrew to improve combat readiness.

Personnel: 9,500

Part of the United States Air Force’s Air Combat Command, Nellis Air Force Base provides almost 13,000 square miles of restricted airspace and ranges for military flight operations. Nellis provides a wide array of aircraft for its primary mission, advanced combat aviation training for fighters, bombers, refuelers, close-air-support, combat search-and-rescue, command-and-control, and transport.

To support this mission, Nellis employs around 9,500 military and civilian personnel. The huge number puts it among the single largest employers in Southern Nevada. In addition, the economic impact of the base includes more than 40,000 military family members and retirees living inside the base.

Nellis made its mark in World War II, turning in more than 215 copilots and 600 gunners every 5 weeks during the height of the war. Nellis started out as the Las Vegas Army Air Field in late 1941.

Established in 1942 to test and train with World War II tank destroyers, Fort Hood has since played many roles for the U.S. military, from testing new equipment, tactics, and introduction of new organizations. It played a crucial role in the Army deployments to the Middle East during the 1990s and 2000s.

As a major military installation, Fort Hood has earned some unique and enigmatic reputation throughout the years. Specifically, it has found itself in the middle of investigations because of sexual misconduct and procedural violations among its soldiers and officers. As well, the very name of the base has come under intense scrutiny for those who want to abolish the practice of naming U.S. military bases after Confederate generals. As it is, the base was named after the Confederate General John Bell Hood, who commanded Hood’s Texas Brigade during the American Civil War. On the other end of the spectrum, Fort Hood is also renowned for widely supporting antiwar activities.

23. Fort Polk

Fort Polk

State: Louisiana

Service Branch: Army

Physical Size: 309.4 square miles (198,000 acres)

Personnel: 13,711

Starting as the base for the Louisiana Maneuvers in the 1940s, Fort Polk figured prominently as a basic and advanced training post during the Vietnam War in the 1960s and 70s. A small area of Fort Polk with jungle-like vegetation and environment that are similar to Vietnam and much of Southeast Asia served as a crucial training ground for Vietnam-bound units at this point. It is for this reason that Fort Polk sent more soldiers to Vietnam than any other American military base during the period. Soldiers often refer to this training area as Tigerland, with Fort Polk being the only stateside Army post many of them saw before being shipped overseas.

During World War II, the base also served as a military prison for German soldiers captured during battle operations. In 1955, the U.S. military conducted Operation Sagebrush to evaluate the performance of the U.S. armed forces during a nuclear environment. Lasting 15 days and involving 85,000 troops, the military exercise covered a significant portion of Louisiana.

Currently, the following units call Fort Polk home: the Joint Readiness Training Center, the 1st Battalion, 509th Infantry Regiment, the 3rd Brigade Combat Team, 10th Mountain Division, U.S. Army Garrison, 115th Combat Support Hospital, the National Guard, and the Bayne-Jones Army Community Hospital.

U.S. Military Bases and Installations – Overseas

With the U.S. reeling from the raging Coronavirus pandemic and mounting national debt, it is no wonder that the government is doing all it can to stave off the looming threat of economic collapse.

Among major solutions on the table is the reduction of military spending. The decision would involve closing military bases and installations in the U.S. and elsewhere around the world and reducing the number of active military personnel.

Nevertheless, the U.S. still maintains a gigantic military presence all over the planet. While the reduction of active forces continues, the U.S. still retains a substantial number of military personnel abroad unmatched by any other nation. This is clearly shown by the following chart:

Source: Defense Manpower Data Center; Statista

Meanwhile, the major U.S. military bases and installations overseas are still forces to reckon with, reduction in military spending and a series of reorganizations notwithstanding. In fact, we have picked the top 10 U.S. military bases around the world in 2021 according to their physical size to show how it is so.

Major U.S. Military Bases and Installations Are Not Going Away Anytime Soon

Despite sharp criticisms of the continuing operations of the vast U.S. military-industrial complex domestic and abroad, there is no reason to expect that the U.S. will reduce them to a size that would be detrimental to its overall global economic and political interest. Historically, American power resides at the intersection of economic and national security. While the old specters of Soviet Russia and communism are long gone, the fast emergence of China as a global economic and military power will hold any call for the substantial reduction of American military influence at bay.

Russia, meanwhile, remains an enigmatic power whose global intentions and actions continue to arouse suspicion and sharp reaction from the power corridors at Washington. Finally, countries like North Korea, Iran, and the shifting military and political dynamics at play in the Middle East ensure that the global role of the U.S. military will not really diminish soon.

In the U.S., it means, among other things, finding a way to resolve the massive problem of student loan without cutting deeply into the budget allocated for militarily securing the global interests of the country.

Another national dilemma, the rising tide of student crime, will have to bide its time.
