Explained: Why No One Can Stop the U.S. Army in a War

Key point: These high-tech weapon systems are what gives America its force-multiplying edge.

When it comes to lethal weapons, the U.S. Army has no shortage. Some may be too expensive, some too complex and others may be desired by politicians and defense contractors, but not the troops on the field.

Nonetheless, today's U.S. Army can generate an astonishing amount of firepower and deliver it in a variety of settings from small-war counterinsurgency to big-war mechanized combat. With that in mind, here are some of the best U.S. Army weapons:

AH-64 Apache:

Ironic it is that the best weapon of America's premier land force is an aircraft. But given the conflicts the U.S. military has recently fought and is likely to fight, airpower is the most decisive factor.

Equipped with a 30-millimeter cannon, Hellfire missiles and sophisticated sensors, the Apache combines speed, firepower and range that allows the Army to strike enemies long before they come within firing distance of Army ground troops. It is equally useful at hunting down insurgents or decimating enemy armored columns. The Apache has fought well in conflicts from Desert Storm to the current Afghan war.

Perhaps more important, the Apache is airpower that the Army itself controls, rather than having to rely on the Air Force or Navy aircraft for close air support. An attack helicopter is not, and will never be, a substitute for infantry on the ground. But the ground troops will appreciate the support an attack helicopter can provide.

M-1 Abrams:

Whether the M-1 Abrams is the best tank in the world depends on who you talk to, and more important, what country they are from. But it is indisputably among the world's best.

Weighing in at 60 tons, the M-1A2 has a 120-millimeter cannon, depleted-uranium armor up to three feet thick and a top speed of more than 40 miles per hour. It decimated Iraq's Soviet-made armor in 1991, and quite possibly would do the same to China's advanced Type 99 tank. Very few Abrams have been destroyed in combat; the fact that ISIS has destroyed or captured Iraqi government M-1s says more about the quality of the crews than the tank.

M-109A6 Paladin:

The U.S. Army's hard-hitting, self-propelled howitzers have taken a backseat in America's recent small wars. Nonetheless, they remain highly potent weapons.
