The M72 LAW (Light Anti-Tank Weapon) is a portable, one-shot, 66mm unguided anti-tank weapon that was first developed in the early 1960s.
It gained a reputation for its lightweight design, allowing infantry to carry it more easily compared to earlier anti-tank systems.

The LAW was designed primarily for use against armored vehicles, and its warhead was effective against light to moderate armor.
The original M72 warhead could penetrate approximately 10 inches of RHA (Rolled Homogeneous Armor), while the improved M72A2 model could penetrate even more.
The M72 LAW has been used in numerous conflicts since its inception, including the Vietnam War, Gulf War, and in various peacekeeping operations.
Its simplicity and effectiveness have made it a staple in military arsenals around the world.
The design of the M72 LAW incorporates a fin-stabilized projectile that provides increased accuracy when fired.
The warhead uses a shaped charge to maximize armor penetration upon impact, which is a principle rooted in applied physics.
There was a training variant of the M72 designated as the M190, which used a non-explosive training rocket to mimic the firing of the standard LAW without the risks associated with live munitions.
The outer casing of the M72 LAW is designed to be lightweight yet sturdy, a crucial factor in military applications.
The material used for the launcher is usually a type of fiberglass or polymer, which allows for easy transport and handling.
The M72 LAW can be classified under the broader category of disposable rocket launchers.
These weapons are designed to be used once and then discarded, which simplifies logistics for infantry units.
In many jurisdictions, deactivated or inert versions can be legally owned without a special license, but laws vary significantly by country and region.
The process of obtaining a surplus M72 LAW often involves online military surplus retailers, auctions, or military collectors.
Prices can vary widely based on condition, model, and legality, with some inert examples being more affordable than expected.
Surplus military equipment like the M72 LAW often undergoes a deactivation process to render it safe for civilian possession.
This process can involve cutting or drilling into the weapon to ensure it cannot be fired again.
The sound of the LAW being fired is distinctive, producing a loud report that is often described as a cross between a gunshot and a small explosion.
The speed of the projectile is around 300 meters per second, which is substantial for a shoulder-fired weapon.
The M72 LAW has been replaced in many modern armies by more advanced anti-tank guided missiles (ATGMs), which feature improved guidance systems that allow operators to engage targets at greater ranges with higher accuracy.
A key aspect of the M72 LAW's usability is in its training; soldiers must practice extensively to understand its trajectory and limitations, as the projectile is unguided and relies on the operator's skill for accuracy.
The original design was influenced by the need for a weapon that was light enough to be carried by individual soldiers but powerful enough to neutralize enemy armored vehicles effectively.
This balance of weight and power is a significant consideration in military engineering.
The M72 LAW was produced under license in several other countries, which contributed to variations in design and performance characteristics tailored to specific military needs.
A peculiar fact is that the M72 LAW was often used by both US and allied forces with little modification despite differences in operational doctrine, showcasing its versatility and global applicability.
The presence of surplus LAWs on the market can sometimes attract collectors interested in military memorabilia, given its iconic status and historical use in various conflicts.
Many anti-tank weapons, including the M72, rely on the principle of momentum and energy transfer to achieve their lethality.
Upon impact, the shaped charge warhead focuses explosive energy on a small point, causing a significant armored breach.
Although classified as a man-portable weapon, the effective range of the M72 LAW is limited to around 200 meters, reflecting the trade-off between ease of transport and engagement distance.
Lastly, the M72 LAW is a symbol of Cold War military technology, representing a shift toward lightweight, easily deployable systems that enabled rapid military response during a time characterized by escalating tensions between superpowers.
